OpenLST is an open source, proven radio design for communicating with remote instruments, vehicles, and stations using low-cost commercial components.

Planet developed the Low-Speed Transceiver (LST) for UHF telemetry, command, and control for the Dove satellite.

Over 100 on-orbit Dove satellites use the LST today.

OpenLST draws on Planet’s experience and success with the LST hardware and firmware.

Planet has used its LST UHF radio on over 200 Dove satellites. Based on commercial hardware, the LST has several hundred cumulative years of on-orbit operation.

The LST has an outstanding success record (with over 200 cumulative years of on-orbit operations) despite having a component cost of < $50.

OpenLST is an open source, proven radio design for communicating with remote instruments, vehicles, and stations using low-cost commercial components.
