Introduction
The PYXIS tracker is a free-flight model aircraft recovery system based on the Global Navigation
Satellite System (GNSS), which uses multiple satellite networks such as GPS, GLONASS, Galileo,
Beidou and other regional systems. It does not require the user to transmit any data, operates
independently of any telephone or Internet reception, and works anywhere on earth where there
is free line of sight to four or more satellites.
The PYXIS tracker consists of a receiver (handheld unit) and a beacon (transmitter installed on the
model). Each unit has its own GNSS module which makes it aware of its position. A long-range
radio link allows the transmission of the model's position to the hand unit which, in combination
with the data from a local electronic compass, displays the distance and the bearing in a straight
line to the model, whatever the path taken for the approach.
