[jamsat-bb:14589] AMSAT Phase3-Eのトランスポンダ周波数プラン
JJ1WTK 坂本です
今日届いたAMSAT-UKの会報 OSCAR NEWSに、製作が進んでいる AMSAT Phase3-E
衛星のトランスポンダ周波数の最終的な案について DB2OS, Peter が書いた記事が
掲載されていましたので、紹介します。
47GHz帯のことは、Rバンドと言うんですね..知らなかったです..
P3E 周波数案 (DL6DBN, 03-10-01) 第4次案
----------------------------------------
GB ジェネラルビーコン
EB エンジニアリングビーコン
PB パスバンド
RUDAK (読みはル−ダック)マルチモードのデジタル中継器
29MHz Uplink (A)
---------------
RUDAK: 29.500 +/- 5 kHz (multi-mode, low-speed)
PB: 29.325 +/- 25 kHz (linear)
145 MHz Downlink (V)
------------------
GB: 145.812 (PSK 400b/s)
EB: 145.957 (PSK 400b/s)
RUDAK: 145.837 (multi-mode, low-speed)
PB: 145.845 to 145.948 (linear)
435 MHz Uplink (U)
-----------------
RUDAK: 436.200 to 436.350 (multi-mode)
PB: 436.020 to 436.150 (linear)
1260 MHz Uplink (L1)
-------------------
RUDAK: 1268.775 to 1268.925 (multi-mode)
PB: 1268.600 to 1268.750 (linear)
1260 MHz Uplink (L2)
-------------------
RUDAK: 1260.275 to 1260.425 (multi-mode)
PB: 1260.100 to 1260.250 (linear)
2400 MHz Downlink (S)
--------------------
GB: 2400.250 (PSK 400 b/s)
EB: 2400.500 (PSK 400 b/s, high speed option)
RUDAK: 2400.600 to 2401.000 (muilt-mode, low/high speed)
PB: 2400.275 to 2400.425 (linear)
5650 MHz Uplink (C)
-------------------
PB: 5668.600 MHz +/- 25 kHz (linear)
24 GHz Downlink (K)
----------------------
PB: 24048.300 MHz +/- 25 kHz (linear)
Beacon: 24048.350 MHz
47 GHz Downlink (R)
-------------------
PB: 47088.300 MHz +/- 25 kHz (linear)
Beacon: 47088.350 MHz
2450 MHz Uplink (S) - 10450 MHz Downlink (X)
---------------------------------------------
TBD
This is the P5A experimental coherent transponder.
It will need a fix frequency relation for coherent
mode and appr. 2 MHz bandwidth for ranging mode.
It will be configurable as linear transponder too
with approximately 50 kHz passband width.
