RK-104, is an excellent GPS L1 band signal Reradiator 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 Reradiator 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 reradiating helix antenna.
Excellent Signal Reception: Re-radiating distance is around 10 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.
THE INDOOR ANTENNA MUST BE TOTALLY ISOLATED AND DOES NOT HAVE A LINE OF SIGHT TO THE EXTERNAL GPS ANTENNA, SO AS TO AVOID FEEDBACK RELECTED RF SIGNAL.
Re-radiating Distance: around 10 meters from the re-radiating antenna
