The CubeSatSim Lite is available again on the AMSAT Store!

This open source hardware and software project runs on a Raspberry Pi Zero 2W and transmits realistic satellite telemetry in the 70cm ham radio band.

I really enjoying developing this STEM educational project!

I finally released the v2.2 software for CubeSatSim, the AMSAT CubeSat Simulator. This release was way too much work. It had too many bug fixes and new features. I need to push releases more frequently, as testing took forever and I kept finding bugs.

I’m very happy with the release. Combined with having more CubeSatSim Lites available, it is an important step for the project!

The 43rd Annual AMSAT Space Symposium is underway in Phoenix, Arizona!

There is a livestream on YouTube https://youtube.com/live/oAC9_Uh2ys4?feature=share

My #CubeSatSim presentation is tomorrow morning.

I enjoyed watching on YouTube Patrick Wood as the Keynote Speaker at the AMSAT-UK 2025 annual colloquium this morning. He did live demonstrations of his CubeSat Simulators which was awesome!

We got a reprogrammed RS-41 radiosonde working with our ground station today:

A different one failed to be received on our last weather balloon launch by the #Villanova #CubeSat Club the other week.

The Villanova CubeSat Club balloon payload was recovered by Pavel in North East Philadelphia about 1.5 hours after launch. He chased it down then called my number from the “Harmless Scientific Experiment” label stuck on the outside.

The Villanova University CubeSat Club High Altitude weather balloon is off the ground!

That was an amazing high altitude weather balloon flights yesterday by the #Villanova University #CubeSat Club!

Here is the dashboard summary of the flight from Sondehub.org:

This is one of the GPS trackers on the balloon. 🎈It transmits on the standard #APRS frequency of 144.39 MHz into a twin lead J-pole antenna. The Raspberry Pi Pico reads the BME280 (temperature, pressure, humidity, altitude) and MPU6050 (gyro and accelerometer) sensors. The transmitter is an SR_FRS_0V5 FM module that transmits 500 mW. The PCB is a #CubeSatSim Beta V2 board. The GPS is a LC76G with a dipole antenna.

#Villanova University students will be launching two high altitude balloons Wednesday May 3 around midday. We will have #APRS & GPS trackers, live #SSTV images, & a #radiosonde! #AMSAT #STEM #CubeSatSim #W3YP #HAB

I will post links to the trackers here so anyone can follow along. If you are a ham or have an SDR or scanner in the Philadelphia/New Jersey area, I’ll post the frequencies so you can listen.

Wish us luck! 🎈📡👍🏻😁
