RA-200
概要
L1-Signal GPS reradiator kit designed for receiving GPS signals indoor
- Fully waterproof at IP66 rating
- Cable length as long as 40m RF cable
- Re-radiating range as long as 20-30m
RA-200, enhanced version of our best-selling RA-200 with a wider re-radiating range of 20~30 meters, is an excellent GPS L1 band signal re-radiator featuring dual antennas to re-transmit real-time GPS satellite outdoor receptions to an indoor environment. Designed to operate as a whole, the system kits are composed of a highly-sensitive external GPS antenna, precisely calibrated amplifier circuit with Helix type indoor re-radiator antenna and a built-in power supply regulator. The Helix type indoor antenna system allows multiple GPS receiver users to perform on-the-fly normal receiver operation within a closed environment, while the main GPS antenna is installed on an unmanned location outdoor. The GPS L1 signal is a 1575.42 MHz frequency; along with a 1.023 Mbps Bi-Phase shift Keying (BPSK) modulated spreading code. The input signal power at the receiving antenna is approximately -130 dBm (spread over 2 MHz). In addition, the unit is designed as plug-n-play hardware and it can be installed either permanently to a secured location or quickly at users' convenience by using either screw mounting or glass suction cup, respectively, for the indoor re-radiator helix antenna.
キャラクター
- Excellent Signal Reception:
Re-radiating distance is around 20~30 meters from the re-radiating antenna. In addition, full receiver visibility of GPS satellites outdoor comes along with an amplified re-radiated signal indoor. - Highly Integrated System:
Designed to operate as a whole, the system kits are composed of a high-gain external GPS antenna, a precisely calibrated amplifier circuit with a Helix type indoor re-radiating antenna and a built-in power supply regulator that provides systems with power. The unit is designed as plug-n-play hardware and it can be installed either permanently to a secured location or quickly at users' convenience by using either screw mounting or glass suction cup, respectively, for the indoor re-radiator helix antenna. - Efficiency & Convenience:
The re-radiator transmits real time data throughout the vehicle directly to an unlimited number of users. Multiple GPS receivers or hand-helds can share just one re-radiator to receive timely data. - Power Saving:
Thanks to its GPS Power Saver design, the system uses an independent power supply source, saving users from the need of other power source for their GPS unit. - Easy-to-Setup:
No additional cables are required and no external GPS antennas are needed to be plugged and unplugged when using a GPS receiver inside the vehicle.
Application:
- Laboratory
- Offices
- Various kinds of transportation means, suchas as trucks, trains, ships sailing boats & buses
