Skytraq GPS/GNSS/IRNSS/NAVIC/GAGAN Break Out Board Module - S1216F8-GI3

Skytraq S1216F8-GI3 GPS/GNSS/IRNSS/NAVIC/GAGAN Break Out Board Module is a Breakout Board having satellite navigation receiver, capable of supporting band L5-NavIC (India) and L1-GAGAN/GPS/GLONASS signals to provide 3D navigation. It has optional mounting of IMU sensors for Dead Reckoning applications and can also support optional RTK module. SkyTraQ chipset combined with best board level RF design of BOB and matched antenna, offers superior cold start sensitivity that allows to acquire, track, and get position fix autonomously even in difficult and weak signal environments.

The S1216F8‐GI3 is a satellite navigation receiver capable of using L5 NavIC, L1 GAGAN/GPS/GLONASS signal to provide 3D navigation in a single compact SMD module. The S1216F8‐GI3 has 56 tracking channels and could track all in‐view satellites. It is fully autonomous such that once power is applied, the receiver automatically searches, acquires, and tracks satellite signals. When a sufficient number of satellites are tracked with valid measurements, the receiver produces 3D position and velocity outputs.

NavIC + GPS/GLONASS triple‐satellite capability enables using a greater number of satellite signals than GPS‐only receivers. The increased satellite number offers superior performance in challenging urban canyon and multipath environments.

The S1216F8‐GI3 module contains SkyTraq Venus 8 positioning engine inside, featuring high sensitivity, low power consumption, and fast TTFF. The superior cold start sensitivity allows it to acquire, track, and get position fix autonomously in a difficult weak signal environment. The receiver’s superior tracking sensitivity allows continuous position coverage in nearly all outdoor application environments. The high-performance signal parameter search engine is capable of testing 16 million time‐frequency hypotheses per second, offering superior signal acquisition and TTFF speed.
