RGM-2106 Operational Manual

1 Introduction

RoyalTek RGM-2106 is the smart antenna GPS module with SiRFstar IV GPS solution.

The module embedded active Jammer remover to ensure fast and accurate navigation in

hostile signal/high noise environment. Power by the new SiRFStar IV architecture, the module

can acquire satellites as low as -163dBm better than SiRF Star III. The high sensitivity, low

power, 48-channel GPS module is the best choice to be embedded in a portable device such

as Car tracking device, Locator application, safety alarm device, personal locator and digital

camera.

Product Features

Wire to board connector type

Additional 3 dB in track sensitivity is better than the Sirf Star III.

Support MEMS Sensor to detection and wake up the device for power saving and longer

battery life.

Adaptive Micro-power controller- only 50 to 500uA to maintain hot start capability.

Embedded InstantFix CGEE and Reverse CGEE (3 days) for faster warm start.

Embedded active Jammer remover to ensure fast and accurate navigation in hostile

signal environments – GSM, NB environments

1.1 Product applications

Personal Navigation Device including GPS PDA and GPS Handheld

Pet/personal Tracker, AVL / Location-Based Services Tracker

Cameras / Digital camcorder

Note:

zV_1V8 (DC 1.8V@ 5% power Input)

This is the DC power supply input pin for GPS system. It provides voltage to module.

zGND

GND provides the ground.

zRXD

This is the main receiver channel and is used to receive software commands to the

board from SIRFdemo software or from user written software.

zTXD

This is the main transmitting channel and is used to output navigation and measurement

data to SiRFdemo or user written software.

zPPS (TIMEMARK)

This pin provides one pulse-per-second output from the board, which is synchronized to

GPS time. Need firmware supporting. If don’t used, can open.

Note: At present PPS function has not opened.

zPower

Connect VCC_IN_1V8 pin to DC 1.8V. The power supply must add bypass capacitor

(10uF and 1uF).It can reduce the Noise from power supply and increase power stability.

zShutdown

Shutdown the RGM-2106 module, don’t remove the Vcc_IN_1V8 Pin, must be use on/off

pulse make it into Hibernate mode.(It’s will keep the Warm start and Hot start function

work well)

zON/OFF

Input pulse is required to start the system, and switch the operation mode tofull-power

mode or Hibernate mode.
