S2532DR Overview
The S2532DR GPS Dead-Reckoning receiver module combines GPS
position data, gyroscope data (measuring turning angle), and odometer
data (measuring distance traveled) to formulate position solution. This
enables accurate navigation solution in poor signal environment or signal
blocked area such as inside tunnels. The S2532DR is ideal for applications
requiring accurate continuous navigation with 100% availability.
The S2532DR features 65 channel GPS receiver with fast time to first fix and
improved -148dBm cold start sensitivity. The superior cold start sensitivity allows
it to acquire, track, and get position fix autonomously in difficult weak signal
environment. The receiver’s -161dBm tracking sensitivity allows continuous
position coverage in nearly all application environments. The high performance
search engine is capable of testing 8,000,000 time-frequency hypotheses
per second, offering industry-leading signal acquisition and TTFF speed.
