Technique description
REB-2100
General information.
The REB-2100 is a
stamp size GPS receiver. It requires +3.3V DC
power input. It can operate with an active
antenna through a MMCX connector. It
provides the antenna power through RF cable.
The default DC input of active antenna is 3.3V
+/- 10%. Since it needs 4 satellites or more to
do the first position fix. The suitable view angle
of the active antenna is necessary. It will
determine the first time position update after a
good satellites geometry (PDOP <= 10). If the
satellites are blocked, it may take time to
determine the position.
Caution: Please do
not put any metal stuff on the antenna.
It
results in GPS receiver getting nothing. In
urban canyon, the fast 0.1 s re-acquisition
capability can make it determine the position
right away through the cross-intersection.
