在网上找了一圈，没有找到ssdv及minimodem的编译好的版本，自己花了点时间编译好了ssdv，minimodem最麻烦，补了一大堆dll文件，不过好在编译好了 ## 版本 - ssdv：2023年4月15日发布的目前最新版 - minimodem：2024年4月18日发布的目前最新版 ## 下载（内容都一样，自行选择下载快的） - [百度云盘（提取码5973）](https://pan.baidu.com/s/1sQsa93yurdP-06pFt8FL8g?pwd=5973) - [蓝奏云盘](https://wwcs.lanzouo.com/iCPyF2xu7ztc) - [github release](https://github.com/super-cookerBH4HZD/ssdv-minimodem-windows-builds/releases)

标题多打了一个“为”字（；´д｀）

之前尝试研究过ssdv这一套体系，但还是云里雾里的。可以简单解释一下ssdv这一套东西目前有什么应用吗？

@"BI1FJK"#p68031 最近刚刚了解，也没有啥实践，可能讲的不对业余无线电通信方面，高空气球和卫星可以带个树莓派和摄像头用ssdv来传输相较于sstv更加清晰的图像，由于其是数字模式，自己接收到的数据包不全可以和别人接收到的数据包拼起来应急通信方面，github上有一个项目叫LoRa-SSDV，说是可以用LoRa模块在灾害现场传图

第一次听说这东西，顶一下

感谢您的贡献！但是minimodem是FSK的调制解调器（包括RTTY）,ASRTU（阿斯图友谊号,AO-123）卫星上那个好像是BPSK的…… 我看了下fsphil/ssdv的使用说明，是不是可以这样理解：我只要想办法把卫星下行的信号（不管是用何种调制方式）的解调还原成（包含了SSDV packets）的二进制数据，我就能扔到fsphil/ssdv程序里面还原出jpeg图片？

非常实用，在Win11上用minimodem测试了Bell202，正常使用，感谢👍

Pre-compiled SSDV and MiniModem executables for 64-bit Windows systems.

I searched online, but couldn't find pre-compiled versions of SSDV and minimodem. I spent some time compiling SSDV myself. The most difficult part was minimodem; I had to install a large number of DLL files, but thankfully, I managed to compile it successfully.

I've tried to understand the SSDV system before, but I still find it confusing. Could you please provide a simple explanation of its current applications?

BH4HZD

BI1FJK I just recently learned about this, and I haven't had a chance to put it into practice yet. It might be that my explanation is not entirely accurate.
In the field of amateur radio communication, high-altitude balloons and satellites can carry a Raspberry Pi and camera to transmit images using SSTV (Single Sideband Television) with greater clarity than traditional SSTV. This is because it uses a digital mode, allowing you to combine incomplete data packets received from different sources.
Regarding emergency communication, there's a project on GitHub called LoRa-SSDV that claims to use LoRa modules to transmit images at disaster sites.

The first time I heard about this, I was really impressed.

Thank you for your contribution!
However, the minimodem is an FSK modulator/demodulator (including RTTY), while the AS RTU (AO-123) on the Asrtu Friendship satellite seems to be using BPSK.

I looked at the usage instructions for fsphil/ssdv. Is it possible to understand that, if I can find a way to convert the satellite-downlink signal (regardless of the modulation method used) back into binary data containing SSDV packets, then I can simply feed this data into the fsphil/ssdv program and it will reconstruct the JPEG image?

JackQChen

Very practical; I tested Bell202 on Windows 11 using minimodem, and it works normally. Thank you.👍
