Device Overview and Specifications
• The RTrak-Lite is the only model in the RTrak family that does NOT have an
internal radio/transmitter. The RTrak-Lite requires the end user to interface it to
any VHF/UHF FM radio of their choice. The main advantage to this is the ability
to use a radio with any transmitting power level and have an internal receiver to
check for channel activity before transmitting.
OpenTracker 1+: The data modem section of the RTrak-Lite is based on the SMT
OpenTracker 1+ platform. The OpenTracker was designed and
programmed by Scott Miller N1VG of Argent Data Systems. The
OT1+ platform is fully open source and a perfect match for the
RTrak-Lite tracker. Firmware upgrades are free for download.
M%5010HS: The GPS receiving chipset used in the RTrak-Lite. This GPS is a
Sirf-Star III receiver with a fast <60 sec cold start lock time,
measures only 10mm x 10mm in size and runs on a 5V operating
voltage.
