SS3 GPS Smart Antenna Module / GM-316
GM-316, SiRFstarIII, 13x16 Tiny & Easy to Use GPS Smart Antenna Module
Overview
GM-316 is a tiny, easy to use, ultra-high performance, low power GPS smart antenna module for handheld applications. It supports both on-board antenna, and an MMCX RF connector. It connects to main board via soldering 6-pin digital interface. The built-in SiRFstarIII chip and our experienced design provide fast acquisitions and excellent tracking Time To First Fix Hot start Velocity Accuracy Horizontal Position Accuracy Receiver Type 20-channel, L1 frequency, C/A code < 2.5m (Autonomous) < 2.0m (WAAS) (50% 24hr static, -130dBm) <0.1 m/s (speed) <0.01 (heading) (50%@30m/s) Autonomous <1sec <35sec <42sec (50% -130dBm) Sensitivity (Autonomous) -142dBm (acquisition) -159dBm (tracking)
