SPL is a global satellite telemetry system for autonomous vehicles controlled by ArduPilot or PX4 autopilots. With SPL you can track, command, and control your solar powered boats, planes, blimps, and other autonomous vehicle from the other side of the Earth.
SPL can use TCP/IP Internet connection or Iridium short burst data (ISBD) satellite communication technology provided by Rock Seven Mobile.
ISBD is a high latency, low bandwidth messaging technology, yet it is relatively inexpensive compared to other global communication solutions. The required hardware is very compact and lightweight.
The SPL software system includes:
- UV Radio Room firmware for autopilot’s companion computer that brokers communication between the autopilot, the Internet modem and ISBD transceiver.
- UV Hub proxy server brokers communication between the ground control stations and the vehicle comm link channels.
- UV Tracks web service provides access to the data stored in the vehicle shadow by UV Hub.
