如题。目前已在软件添加ISS。还有哪些可以使用的卫星？信标，VU段，SSTV，APRS都有哪些常用的卫星？如果想和ISS宇航员通联，需要关注哪个频率/卫星？

其他的不太了解，这里分享下卫星中继通联除了楼主提到ISS以外常用的卫星，如过有误恳请斧正： SO-50（打这个需要考虑极化，打的时候需要除了对准卫星之外，还需要**水平转动天线寻找合适的极化方向**并且要随时调整） PO-101 按时间表计划开启转发器，打之前查一下开不开 ASRTU-1（别名AO-123） LAPAN-A2（别名IO-86，注意**赤道30°以内**才可用） HADES-R (别名SO-124) FOX-1B（别名AO-91）该卫星电池故障只能在**日光下**可用，并且可能突然关机，同时打这颗星也需要和SO-50一样**考虑极化**

SSTV:ISS,RS40S,RS38S APRS:ISS FM:ISS,SO-50 我大概就知道这几个

微信里有很多小程序都是针对微信的，你直接找就行。“HAM个人工具”“云端卫星”我一般就用这两个，主要是为了sstv

常见U/V段FM转发器稳定运行：ISS、SO-50（SAUDISAT 1C）、SO-124（HADES-R）不太稳定：AO-91、AO-123（ASRTU-1）、SO-125（HADES-ICM）

@"ping"#p70462 玩卫星也不定非要玩上行，下行遥测接收也是一个方向。

有的卫星下行接收还可以拿到qsl

@"BG7XSS"#p70545 哪些可以？麻烦指个路。我怎么向他们申请qsl呢

What are some commonly used satellites?

ping

As the title indicates. I have already added ISS to the software. What other satellites can be used? Which satellites are commonly used for beacons, VU band, SSTV, and APRS? If I want to communicate with an astronaut on the ISS, which frequency/satellite should I monitor?

BI1NIZ

ping It's not necessarily required to only transmit and receive data via satellite; receiving data from both up and down links is also a viable option.

BG7LJX

Besides ISS, which was mentioned by the original poster, here are some other commonly used satellites for satellite relay communication that may be useful: (Please correct me if any of these are incorrect)
SO-50 (When using this, you need to consider polarization. In addition to aiming at the satellite, you also need to...)Rotate the antenna horizontally to find the appropriate polarization direction.And it should be adjusted at any time.
PO-101: Operate the transmitter according to the schedule, and check if it's turned on before each transmission.
ASRTU-1 (also known as AO-123)
LAPAN-A2 (also known as IO-86, note)Within 30 degrees of the Equator(Currently available)
HADES-R (also known as SO-124)
FOX-1B (also known as AO-91) – The battery failure on this satellite can only beIn direct sunlightIt's available and may suddenly shut down, and also requires being synchronized with SO-50.Consider polarization

BA4SBF

SSTV: ISS, RS40S, RS38S
APRS: ISS
FM: ISS, SO-50
I had a general idea of these.

bh1cqz

There are many mini-programs within WeChat, all designed specifically for WeChat. You can simply search for them. I usually use "HAM Personal Tools" and "Cloud Satellite," primarily for SSTV (Single Sideband Television).

Common U/V band FM forwarders
Stable operation: ISS, SO-50 (SAUDISAT 1C), SO-124（HADES-R）
Not very stable: AO-91, AO-123（ASRTU-1）SO-125（HADES-ICM）

BG6HMA

nkxingxh The SO-125 is designed for weekend use, so there's no reason to believe it would be unstable.

nkxingxh

BG6HMA Thank you for pointing that out. The above statement simply reflects my conclusions based on observations over a period of time. "Not stable" can be interpreted as meaning "not full-time work".

BI1JNP

CIA-1 and KGB-1

bg5axs

In the "ham" personal tool application, sort by activity level. Welcome to try it out!

BG7XSS

Some satellites can still receive downlink signals and obtain QSL cards.

ping

BG7XSS Which ones are possible? Please point me in the right direction. How do I apply for a QSL card with them?

BG2GQG

FM repeater
Currently, ISS SO50 and SO124 are stable and functional.
Planned startup: AO123, SO125, PO101
(Both AO123 and SO125 are generally open on weekends)
AO91 might turn on in the evening.
(I was able to connect successfully earlier in the evening, which suggests I had just arrived from Zhaodao District. However, even if I turned it on, it might have shut down after only half its operation due to a power issue.)
IO86 cannot be used in Zone 2... I'm not sure.

Ironic

In actual measurements, the probability of successful communication on the SO-50 band is highest when using only a Yagi antenna (specifically, an eight-element Yagi), and this is most likely to occur before 9:00 AM. While it's relatively easy to listen for ISS signals, connecting with them requires a Yagi antenna.

FM星：
ARISS 是比较好用的，常态开机，功率较大（为5w,其余卫星多为0.25/0.5w）。
SO-50（SAUDISAT 1C） 是一颗很老的卫星，但目前依然坚挺，常态开机关机了可能就再也打不开了，需要考虑极化方向（信号不好的时候需要旋转八木以找到正确极化方向），如果在人较少的时间没有持续下行信号用来调整极化方向容易丢下行（对于单工）。
SO-124（HADES-R）今年的新卫星，常态开机，但周三会变成各种数字模式（具体模式会有计划表），缺点是上下行没有哑音（偶尔可以听到被转发的工地信号）以及目前有较多遥测（遥测时无法通联）。
SO-125（HADES-ICM）六月份新开机的卫星，UTC时间周五六日开机，其余情况基本等同于SO-124，但是会有更多遥测。
AO-123（ASRTU-1）中俄合作的卫星，开机时间看哈工大学长心情（bushi，目前来看多在假期开机，遥测量介于SO-124和SO-125之间（个人估计）。
IO-86（LAPAN-A2） 南北纬三十度以内可用，本人用不到，不做评价。
AO-91（FOX-1B）也是老牌卫星，因为电池故障只能在日光下开机，根据个人经验这颗卫星开机很不稳定。其余情况不清楚。不做多余评价。
PO-101（DIWATA-2B）自从我入坑以来（今年三月）只开机过一次，情况本人不清楚，不做评价。
~~其他模式的卫星本人实力太差没用过~~
PS：
关于卫星频率 前六颗卫星为U下V上（应该是较为友好），后两颗为V下U上（从来没打过，但猜测相对来说不容易收到下行信号）。
关于卫星秩序 一般来说人数越少秩序越好。对于卫星个体，除了ARISS人数略多，其余没有大的差距。对于时间段，假期时人数会多，同一天之内晚上较白天人数会多，而凌晨时人数较少（与人预约通联可以在这个时间）。而秩序不好主要指打断他人通联及互压情况（多数人为单工上星，但推荐双工上星）。~~卫星是我家，秩序靠大家~~
关于天线 对于新手使用八木以外的天线纯属折磨自己，推荐使用较多单元的八木（如BH7JYR出品的U7V4）。
关于电台功率 5W是完全够用的，QRO不推荐（QRO一定要保证双工上星！），卫星只能同时转发一个最强的信号，如果没有稳定下行容易对他人造成干扰。
