2026 AMSAT Field Day Next Weekend!

It’s that time of year again; summer and Field Day! Each year the American
Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout,
practice for emergencies, an informal contest and, most of all, FUN!” The
event takes place during a 27-hour period on the fourth weekend of June.

For 2026 the event takes place from 1800 UTC on Saturday June 27, 2026
through 2100 UTC on Sunday June 28, 2026. Those who set up prior to 1800
UTC on June 27 can operate only 24 hours. The Radio Amateur Satellite
Corporation (AMSAT) promotes its own version of Field Day for operation via
the amateur satellites, held concurrently with the ARRL event.

This year should be as much fun as last year since we have more than 10
transponders and repeaters available. For AMSAT purposes, a transponder on
a satellite would count as two if you could do phone and CW. We count them
by modes, not the satellite names.

Users should check the AMSAT status page at http://www.amsat.org/status/
and the pages at https://www.amsat.org/two-way-satellites/ for what is
available in the weeks leading up to field day. To reduce the amount of
time to research each satellite, see the current FM satellite table at
https://www.amsat.org/fm-satellite-frequency-summary/ and the current
linear satellite table at
https://www.amsat.org/linear-satellite-frequency-summary/ .

If you are considering ONLY the FM voice satellites, there are ISS and
SO-50. The congestion on FM LEO satellites is always so intense that we
must continue to limit their use to one-QSO-per-FM-satellite. This includes
the International Space Station. You will be allowed one QSO if the ISS is
operating Voice.

It was suggested during past field days that a control station be allowed
to coordinate contacts on the FM satellites. There is nothing in the rules
that would prohibit this. This is nothing more than a single station
working multiple QSO’s. If a station were to act as a control station and
give QSO’s to every other field day station, the control station would
still only be allowed to turn in one QSO per FM satellite while the other
station would be able to submit one QSO.

The format for the message exchange on the ISS or other digital packet
satellite is an unproto packet to the other station (3-way exchange
required) with all the same information as normally exchanged for ARRL
Field Day, e.g.:

W6NWG de KK5DO 2A STX
KK5DO de W6NWG QSL 5A SDG
W6NWG de KK5DO QSL

If you have worked the satellites on Field Day in recent years, you may
have noticed a lot of good contacts can be made on some of the
less-populated, low-earth-orbit satellites like AO-7, RS-44, AO-73, FO-29
and JO-97. During Field Day the transponders come alive like 20 meters on a
weekend. The good news is that the transponders on these satellites will
support multiple simultaneous contacts. The bad news is that you can’t use
FM, just low duty-cycle modes like SSB and CW.

Satellites Are The New Fire Towers

The Bezos Earth Fund announced a $26 million grant for the nonprofit Earth
Fire Alliance and its satellite-based wildfire detection program, Axios’
Ben Geman reports.

The money — alongside support from Google and others — will help fund the
launch of three FireSat satellites this summer.

The groups say they’ll “provide wildfire monitoring at least twice daily
over critical geographies, including a focus on the Amazon Basin — one of
the most fire-vulnerable regions on Earth.”

The funding is the largest-ever single philanthropic grant for wildfire
detection, the groups say. They add that the program could help protect
homes, communities and biodiversity — and cut CO2 emissions from wildfires
by up to 10% annually.

View, Calif. (Photo: Muon Space)*

Wildfires are a major driver of deforestation, which worsens climate
change. They accounted for 42% of tree cover loss in 2025, per World
Resources Institute data.

The Earth Fire Alliance says it hopes to have dozens of satellites
operating by the early 2030s that can “monitor every point on Earth every
20 minutes.”

Announcing OrbitDeck

A new open-source desktop application called OrbitDeck brings the classic
OSCARLOCATOR into the software age, pairing a faithful recreation of the
beloved paper tracking aid with a built-in classroom of orbital-mechanics
lessons. Written in Python and released under the MIT license, OrbitDeck
runs on Windows, macOS, and Linux — including the Raspberry Pi — and is
tracking-and-analysis software only; radio and rotator control are
intentionally left to the excellent dedicated tools already serving that
role.



*OrbitDeck map screen (Image credit: Paul Stoetzer)*

Longtime operators will remember the OSCARLOCATOR: a polar map overlaid
with a rotating ground-track transparency that let you predict a pass with
nothing but a pencil and a clock. OrbitDeck rebuilds that experience as an
interactive on-screen OSCARLOCATOR. You drag the map to rotate the path-arc
overlay across a polar or QTH-centered base map, watching the satellite’s
position and your station’s footprint move in real time. A protractor-style
rim with per-degree tick marks and longitude and azimuth labels frames the
disc. You can drive the overlay live, position it by hand to any
equator-crossing longitude, drag the marker along the arc to step through
the minutes after the crossing, or seed it directly to your next visible
pass. A compact next-equator-crossings list is built in.

Crucially, OrbitDeck also closes the loop with paper. Any satellite — real
or hypothetical — can be exported as a printable PDF OSCARLOCATOR, ready to
drop onto a clipboard for portable, screen-free operating in the field or
in the classroom.

That classroom focus runs throughout the program. A dedicated Learn section
presents orbital mechanics across grouped, interactive tabs — Kepler’s
equal-areas law, anomalies and the vis-viva relation, nodal precession and
sun-synchronous orbits, slant range and footprint geometry, Doppler
tune-through, eclipse and beta-angle sunlight, a link-budget sandbox, and
element-set aging — each with a live diagram you can manipulate rather than
merely read. A printable “Orbits 101” handout rounds it out.

The standout teaching tool is the lab satellite. From within the
OSCARLOCATOR simulator, you can invent a hypothetical bird and edit its
orbital elements with sliders and entry boxes — altitude (with the period
updating live), eccentricity, inclination, RAAN, argument of perigee, mean
anomaly, and direct apogee and perigee control. The ground track,
footprint, and range circle respond instantly, plain-language explainers
describe the effect of every change, and a gallery of presets loads
recognizable archetypes from ISS-like LEO to Molniya and geostationary.
Design an orbit to a requirement, compare two designs side by side, then
name and print your creation as an OSCARLOCATOR exactly like a catalog
satellite.

OrbitDeck reads modern GP/OMM data, ships its own SGP4 propagator and an
offline catalog so it works without a connection, and is free to download.
It is an inviting on-ramp for newcomers and a genuinely useful operating
and teaching aid for veterans.

Changes to AMSAT TLE Distribution for June 19, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated daily in the first hour of the UTC day. New bulletin
files will be posted immediately after reliable elements become available
for new amateur satellites. More information may be found at
 https://www.amsat.org/keplerian-elements-resources/
<https://www.amsat.org/keplerian-elements-resources/>.

*There are no changes to this week’s TLE distribution.*
General Perturbations Data Support

AMSAT is pleased to announce that modern forms of what are called General
Perturbations data are being disseminated via modern formats including
JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The
reason this change is being made is that we are running out of 5-digit
catalog numbers and the TLE format is not viable for satellites launched
after July of this year. See
https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.

These data are presently considered in beta test for the next two months
while hosted on the test server newark192.amsat.org, and we are very open
to community feedback at webmaster ＠ amsat.org. Testers may experience
outages and errors while we make improvements. We intend to put this into
production on our main web server in July as we expect that satellites
launched after this summer will require one of the new formats to
accommodate longer object numbers. AMSAT will continue to publish TLE
bulletins for satellites launched before July 2026 indefinitely.

Dragon Returns Packed with Space Station Science

Scientists await a big splash in the Pacific Ocean as one of the most
research-packed Dragon spacecraft to date returns, completing the 34th
SpaceX commercial resupply mission to the International Space Station for
NASA. Biological and materials samples, along with tested hardware, are
heading back to research teams on Earth for further analysis, advancing
NASA’s work to prepare humans for exploration beyond low Earth orbit and to
deliver benefits back home.

to study how weightlessness affects crew blood clotting and immune function

Some samples returning are for NASA’s Hematopoietic Stem Cell Expansion in
Space: Pathfinder Investigation (InSPA-StemCellEX-H2), which seeks to use
the microgravity environment to scale up the production of stems cells. On
Earth, lab-produced blood stem cells lose their ability to form different
cell types, like red and white blood cells that are critical to treating
patients with certain blood diseases and cancers. In microgravity,
researchers believe this ability will be better preserved while also
growing these stem cells in greater numbers. The returning samples will
undergo further analysis to determine if space-based efforts produce larger
quantities of enhanced stem cells suitable for clinical use.

The team behind NASA’s Streptococcus pneumoniae (Spn) Infection of Cardiac
Tissue (MVP Cell-09) experiment is awaiting the return of stem cell-derived
heart tissues that were intentionally infected with a pneumonia-causing
bacterium as part of ongoing microgravity research. Pneumonia increases the
risk of heart disease, which is not fully understood. Because bacteria tend
to become more active and virulent in microgravity, this experiment could
amplify their effects, making it possible to detect cellular responses that
cannot be observed on Earth.

NASA’s Megakaryocyte Flying-One (MeF1) samples are returning to Earth to
help understand how large cells found in bone marrow, known as
megakaryocytes, and the platelets they produce adapt to spaceflight.
Megakaryocytes and platelets play important roles in the formation of blood
clots and immune responses. The returning samples, including those taken
from astronauts, could show us how the human immune system reacts aboard
the space station and help prepare for future exploration missions.

Semiconductor research samples as part of NASA’s In-Space Production of
Semimetal-Semiconductor Composite Bulk Crystals in Microgravity
(SUBSA-InSPA-SSCug) investigation are returning to Earth for further
analysis. This study manufactured semimetal-semiconductor composite alloy
crystals in space, which have applications in many electronics, including
sensors and lasers. Researchers believe microgravity could enable the
production of significantly greater and higher-quality crystals, supporting
the development of next-generation semiconductor technologies.

Additional experiments being returned include NASA’s Zero Boil-Off Tank
Noncondensables (ZBOT-NC) investigation, NASA’s DNA Nano Therapeutics-3
space-assembled DNA-inspired materials, NASA’s InSPA-Sachi Nanoligomer
investigation, European Space Agency’s (ESA’s) Green Bone investigation,
NASA’s 3D Bone Marrow Analog research, and NASA’s InSPA-Auxilium
Bioprinter-Cell Printing is investigation. To read more about these
experiments, see the full article at

There is a lot of traffic on Facebook and on other social media sites with
people asking why they are not hearing the crew make general contacts.
First off the crew is very busy on the ISS and they simply may not have the
time to just pick up the microphone and talk. Also, one needs to be aware
of their normal daily schedule:

Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours

The crew’s usual waking period is 07:30 – 19:30 UTC. The most common times
to find a crew member making casual periods are about one hour after waking
up and about an hour before sleeping, when they have personal time. They’re
usually free most of the weekend, as well.

The APRS packet system is also active (437.825 MHz up & down).

Ham TV is currently transmitting a test signal at 2395.00 MHz. *The color
bar test generator portion of the Ham TV system is experiencing unexpected
technical issues. ARISS is working to troubleshoot the issue with NASA’s
payloads support team and the ISS crew.*

As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol. *Radios will be powered down
in support of an upcoming spacewalk in late June: Power down: June 29 at
15:15 UTC Power up: July 1 at 10:15 UTC*

Note, all times are approximate. It is recommended that you do your own
orbital prediction or start listening about 10 minutes before the listed
time.

Satellite Shorts from All Over

+ HamSat (free) and HamSat Pro (one-time purchase), iOS satellite tracking
apps for iPhone/iPad by Vasco Barreiros, CT1OY, have recently been updated
with new features, including compatibility with Apple Watch. HamSat is
available on the iPhone App Store. (ANS thanks Peter Green, GØABI, for the
above information.)

+ The upper stage from a commercial Chinese rocket that launched last week
has broken apart in space, spreading debris in a heavily trafficked part of
low-Earth orbit — home to the International Space Station and a significant
portion of SpaceX’s Starlink broadband network. The breakup occurred
shortly after the Zhuque-2E rocket reached orbit on June 9 with two
satellites providing direct-to-cell communications, perhaps around the time
the upper stage was expected to perform a disposal burn. The U.S. Space
Force confirmed the breakup event stating, “There are currently no threats
to human spaceflight.”* (ANS thanks ArsTechica for the above information.

+ A new paper from researchers at NASA’s Ames Research Center in California
reports that 73.3 percent of images the agency’s new SPHEREx space
telescope collected between May and September of last year were
contaminated by at least one artificial satellite trail. Typically this
type of light pollution is associated with ground telescopes. But SPHEREx
is an orbital satellite about 700 kilometers above the Earth’s surface.
Apparently even that wasn’t enough to escape from the light trails. *(ANS
thanks IEEE Spectrum for the above information. See the full article at
https://spectrum.ieee.org/satellite-light-pollution-spherex-hubble
<https://spectrum.ieee.org/satellite-light-pollution-spherex-hubble>.)*

+ A dazzling fireball streaked through the skies above the Midwest on June
14, crashing through Earth’s atmosphere at a staggering 56,000 mph (90,123
km.h per hour) before burning up. More than 500 witnesses reported the
event to the American Meteor Society,— some of whom uploaded footage of the
fiery event. NASA’s all-sky camera network also captured the fireball from
three locations. *(ANS thanks Space.com for the above information. Read the

+ An Ariane 6 with upgraded solid rocket boosters successfully launched
three dozen Amazon Leo satellites June 17. So far, 367 Amazon Leo
satellites have launched on Ariane 6, Atlas V and Falcon 9. However, there
is only one more Atlas 5 launch for Amazon Leo, scheduled for July 3,
forcing Amazon to lean more on Arianespace. The company still has a July
2029 deadline to deploy the full constellation, as part of the FCC’s waiver
decision on June 5. *(ANS thanks SpaceNews for the above information. If

+ NASA Administrator Jared Isaacman, responding to questions about the
agency’s selection of an all-male crew for the Artemis 3 mission, said the
astronauts were chosen based solely on their experience, skill sets and
availability. Isaacman strongly defended the crew selection, saying he had
“personally been to space twice with 50 percent female crews. My closest
advisors and some of the smartest engineers I know are women. In our latest
NASA leadership organization, nearly 50 percent of the center directors and
mission directorate leadership are women.” *(ANS thanks SpaceflightNow for
