Operational Manual
Introduction
RGM-3000/REB-3000 is the third generation of
RoyalTek GPS Receiver. RGM-3000(E,M)
consists of active antenna and GPS receiver.
REB-3000(or RGM-3000L) consists of GPS
receiver without active antenna. The GPS
receiver is powered by SiRF Star II technology
and RoyalTek proprietary navigation algorithm
that providing you more stable navigation data.
The miniature design is the best choice to be
embedded in a portable device like PDA,
mobile phone, person locator and vehicle
locator. It supports TricklePower function which
can be enabled by external command for
power saving. The excellent sensitivity of
RGM-3000 gets the great performance when
going though the urban canyon and foliage.

General information. The RGM-3000 is a
stamp size GPS receiver with an active
antenna. It provides the antenna power
through RF cable. The default DC input of
active antenna is 2.8 ~3.3V. Since it needs 3
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 getting good satellites
geometry. 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 second
re-acquisition capability can make it determine
the position right away through the
