Iridium Satellite GPS Tracker

Iridium Satellite GPS Tracker Model : TR130 Introduction : TR130 is true global satellite communication system based on iridium SBD and GPRS hybrid technology. It is mainly designed for the high value assets tracking with no blind area on the earth. The device provides real time tracking with lower monthly tracking costs while delivering 100% global coverage and web-based fleet monitoring. It works far beyond the reach of WiFi and GSM network. It works on the top of mountain, the middle of desert, the middle of any ocean, isolated islands, as well as the polar regions. Features: 1. Dual mode communications: Iridium SBD module and GPRS module 2. Auto switch communication mode, GPRS is priority mode. It switches to SBD mode wherever there is no GPRS signal. 3. No blind area: Signals cover all global areas including remote areas, sea, air, mountain, desert and the polar regions 4. Geo-fence Specifications: Iridium receiver parameters Iridium module: Iridium 9602n Frequency: 1616 ～ 1626.5 MHz Receiving sensitivity: -118.5dBm at 50W Global coverage: no blind areas Duplex mode: TDD (Time Division Duplex) Upstream data: maximum length: 340 bytes Downstream: maximum length is 270 bytes Transmission delay: 10 ~60 seconds (because of galaxy switch) Input/ Output impedance: 50Ω Multiplex mode: TDMA/FDMA Iridium antenna and interface: external antenna, SMA interface
