Description

The overall goal of the SilverSat mission is to be an educational mission for middle- and high- school students. This satellite is designed and built by student members of SilverSat with adult mentors. It is a technology demonstration, using emerging Improved Layer 2 Protocol (IL2P) data over amateur UHF frequency to and from the satellite. This extends work that has been done by others with using this protocol for amateur packet radio. SilverSat will employ multiple operating modes for this demonstration.

In SSDV Mode, we will use the Slow Scan Digital Video (SSDV) format to transmit images taken by the satellite. These will be transmitted globally so that operators worldwide can become familiar with the IL2P protocol as well as the SSDV format. All necessary information to receive and process these images will be available on our website. In addition, anyone can request images of a particular location using our website.

In “Tweet from space” mode, the satellite would transmit data in an IP over IL2P protocol. This will transmit photos taken by a camera on the satellite, along with short text. The ground station will forward this data and photos to the media platform X, as tweets. This facilitates outreach to and involvement of those who may not already be involved in amateur radio.
