CAS-7B Launched and Operational

On July 25, 2019, CAMSAT's CAS-7B satellite was successfully launched
on the first orbital launch of iSpace's Hyperbola-1 rocket.

CAS-7B is in a very low earth orbit with an apogee of 296 km and a
perigee of 278 km. The inclination is 42.7 degrees. At this altitude,
decay is expected by August 11th.

CAS-7B carries a 100 mW CW telemetry beacon at 435.715 MHz and an FM
transponder with an uplink of 145.900 MHz (16 kHz bandwidth, no tone
required) and a downlink of 435.690 MHz (100 mW).

Many QSOs around the world have been reported via the FM transponder.
Reports indicate the transponder requires a considerable amount of
EIRP to access and that the satellite is spinning fast causing rapid
fading of signals.

More information about CAS-7B can be found at

Upcoming ARISS SSTV Events

ARISS Russia plans to activate the MAI-75 SSTV experiment on July 29
with images starting at 13:15 UTC ending at 21:25 UTC, then again
starting July 30 at 13:50 UTC ending 19:30 UTC. Downlink frequency is
145.800 MHz FM using the PD-120 SSTV mode.

ARISS plans to commemorate Owen Garriott's outstanding accomplishments
with ham radio in space during an ISS SSTV event starting 09:40 UTC on
August 1 and ending 18:15 UTC on Aug 4. Downlink freq will be 145.800
MHz FM using the PD-120 SSTV mode.

However, there is a possible switch out in images for SSTV event
scheduled for August 1-4. This may result in planning an additional
SSTV event for the end of August that would feature the Owen Garriott
commemorative images at that time. We expect an update on this after
July 26th

AMSAT-Chile developing CESAR-1 FM / digital satellites

AMSAT-CE is designing and building five satellites, to be used by
radio amateurs around the world, which will allow a series of
scientific experiments in the field of digital communications, as well
as gravimetric and orbitgraphic studies.

Of these five satellites, one will be the engineering prototype, three
will be flight units, and the remaining one will be used to check or
replicate on the ground the operation of the units that are in space.

AMSAT-CE has also promoted the installation of three earth stations,
in Iquique, Temuco and Pto. Montt.

Technical characteristics

*CESAR-1 is of microsat technonogy (cube shape, 23 cm per edge).

*The satellite reception frequencies will be in the 145 MHz band
(5 channels) and 1,575 MHz (GPS).

*The satellite transmission frequencies will be in the 436 MHz band
(2 channels).

*The modulation will be FSK (AX.25 9.6 kbps) or narrowband FM.

*The magnetic stabilization will be by permanent magnets.

*It will have a magnetic brake (the rotation due to the photonic spin
will be stopped by seven bars of hydrogen steel, which will cut lines
of force from the earth's magnetic field).

*The estimated useful life is 10 years.

*The mass will be approximately 12 kg

*The period will be 100 minutes (that's about 14 revolutions a day).

*The satellite platform consists of 5 modules made of space aluminum

*The electrical energy will be stored in a Saft NiCd battery, made up
of 8 batteries of 7 Ah each.

*The solar cells will be Spectrolab, triple junction (GalnP2-GaAs-Ge),
or the like.

Contributions of the CESAR-1 Project to the Country

AMSAT-CE satellites will be added to the projects already undertaken
by the Chilean Air Force (FASAT) and the University of Chile (SUCHAI),
but they have as their main characteristic that they are the first
ones that are being designed and built entirely in the country, which
constitutes a huge challenge, and a scientific and technological

Among the benefits that the country and the amateur radio can obtain
from AMSAT-CE satellites are:

- Education (interest young people in space radiocommunications)
- Support in emergency situations
- Scientific experimentation (in the frame for experiments)
- Boosting a national aerospace industry
- Experimentation with the Internet
- National Amateur Radio Unit, and
- International recognition for the country.


The CESAR-1 satellite will have five main (E) experiments:

E1 A digital transponder between two earth stations, to be used in
real time, during the period in which both are being illuminated by
the satellite (radio-packets in AX.25 at 9,600 kbps).

E2 A digital transponder between two earth stations, to be used in
deferred time, as an electronic message box (Store & forward with
radio-packets in AX.25 at 9.6 kbps).

E3 An analog repeater that will allow two earth stations that are
being illuminated by the satellite to be linked, to broadcast audio
(voice) in real time, in FM mode.

E4 Communication between two terrestrial repeaters, with link to the
satellite, which will allow long distance, but temporary, calls to
low-power portable stations (voice, FM, 147 MHz access), and

E5 An on-board GPS receiver, which will collect information for
gravimetric and orbitgraphic research.

The orbit of CESAR-1 will be low, polar and heliosynchronous
(about 800 km high).

*In any case, given the time elapsed, it is possible that both the
experiments and the electronic part considered for them must be

Cost of the Project and its Financing

The cost of the project, in money, amounts to about USD 700,000
(necessary for the construction of five satellites, launch of one,
implementation of two command and control stations, and three
terrestrial repeaters).

Of that amount, around USD 300,000 have already been contributed by
external sponsors, and by members of the AMSAT-CE Foundation.

However, we have not yet been able to obtain the financing of the
remaining USD 400,000

Additionally, and conservatively, we estimate that the project
requires some 36,000 man-hours of managers and specialists.

Much of those 36,000 hours have already been or are being voluntarily
contributed by the AMSAT-CE partners.

Essentially, the monetary resources that are still missing are needed
to finance the solar cells of CESAR-1, hire professional services to
finish the construction of what is pending, and cover the costs of
the tests and the first launch.

Project status

Although it is a radio amateur project, it does not cease to
correspond to a professional and complex project.

But the more than 20 years we have been working - without reaching the
goal - have exhausted some of our partners, and this has generated a
shortage of volunteers.

It has not been easy to finish the first satellite - which should have
flown in the late 1990s - because in Chile there is still not enough
awareness about the possibilities offered by space activity to the

Despite this, the construction of CESAR-1 is quite advanced (more
than 70%):

-5 mechanical satellite structures are built.
-8 UHF transmitters are finished, and aligned in their working
-The sources of power are finished.
-The receivers have an advance of 90%.
-The GPS experiment has an advance of 70%.
-In the OBC with its EDAC and RAM disk, the software needs to be
-The international coordination of frequencies in the ITU was
concluded, but today it would have to be reactivated, for the time
-There are, yes, the photovoltaic cells, the assembly in Chile and the
final tests (which will probably be done in Brazil).
-It is also necessary to reactivate the obtaining of the pitcher.
