GM-301, SiRFstarIII Ultra-High Performance GPS Smart Antenna Module
Overview
GM-301 is an easy to use, ultra-high performance, low power GPS smart antenna module with patch antenna for AVL/handheld applications. The built-in SiRFstarIII chip and our experienced design provide fast acquisitions and excellent tracking performance. Velocity Accuracy Horizontal Position Accuracy Receiver Type 20-channel, L1 frequency, C/A code < 2.5m (Autonomous) < 2.0m (WAAS) (50% 24hr static, -130dBm) <0.01 m/s (speed) <0.01 (heading) (50%@30m/s) Time To First Fix Hot start Warm start Cold start Autonomous <1sec <35sec <42sec (50% -130dBm)
Applications
Automatic vehicle location Personal navigation devices Fleet management GPS clock and digital camera Child/elderly/personal locator and security system
Features
Based on SiRFs GSC3f low power single chip High performance: -159dBm tracking sensitivity Low power: 42mA at continuous tracking Push to fix reduces power by as much as 98%. SBAS (WAAS and EGNOS) support Easy to use: built-in patch antenna & 6-pin wire to board connector w/ pitch of 1.0mm Backup battery support for faster position fix Blue LED for position fix indication Fully EMI shielded
