1. Introduction

1.1 Overview

Rikaline
The GPS-22 GPS Receiver is a GPS receiver featuring the revolutionary FirstGPS™
architecture. This complete enabled GPS receiver module provides high position and speed accuracy
performances as well as high sensitivity and tracking capabilities in urban canyon conditions. The solution
enables small form factor package. The GPS-22 delivers major advancements in GPS performances,
accuracy, integration, computing power and flexibility. It is designed to simplify the embedded system
integration process.
This positioning application meets strict needs such as car navigation, mapping, surveying, agriculture and
so on. Only clear view of sky and certain power supply are necessary to the unit. GPS-22 communicates
with other electronic utilities via compatible dual-channel through TTL and saves critical satellite data in
built–in memory backup. With low power consumption, the GPS-22 tracks up to 8 satellites at a time,
re-acquires satellite signals in 100 ms and updates position data every second.

1.2 Features

The GPS-22 provides a host of features that make it easy for integration and use.
1. Position accuracy in < 3m CEP (50%) or <5m CEP ((90%) without SA (horizontal)
2. Ultra low power: 17mA typical -- tracking at 3.3 Volts, full power
3. High sensitivity: to -143 dBm tracking, superior urban canyon performances
4. Small form factor and low cost solution
5. Ready-to-plug solution. Easily integrated into existing systems
6. On-board RAM for GPS navigation data
7. PPS output (User may have different interval setting from 1 second to 1 minute.
8. Differential capability utilizes real-time RTCM corrections producing < 1 meter position accuracy.
9. FLASH based program memory: New setting is stored permanently.
