1. Introduction
1.1 Overview
The
Rikaline
GPS-24 / 24A is a GPS receiver board featuring Nemerix low power
architecture. This
complete enabled GPS receiver board 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-24 / 24A 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-24 / 24A
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-24 / 24A tracks up to 16
satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second.
1.2 Features
The GPS-24 / 24A provides a host of features that make it easy for integration and use.
1. Position accuracy in < 7m CEP (90%) without SA (horizontal)
2. Ultra low power: 30mW typical -- tracking at 3.3 Volts, full power
3. High sensitivity: to -152 dBm tracking, superior urban canyon performances
4. Small form factor and low cost solution
