GPS/GNSS Distribution System iRGS232


【Description】

  • The iRGS232 GPS Splitter is a dual-input, thirty two-output GPS device. The dual input ports connect two GPS receive antennas. The outputs ports grant up to 32 GPS receives signal access at one time .
  • When entering the GNSS signal system management terminal to set the IP, the software can display the power of each port , the number of GPS visible satellites and the value of C / No , the number of Beidou visible satellites and the value of C / No .
  • This product typically finds application where an input from an active GPS roof antenna is split evenly between thirty two receiving GPS units. Usually the iRGS232 is configured with an 12V input (48V telecom power input also available ) . In this scenario, the iRGS232 can be configured to pass DC from an RF output (J1) to the antenna input port in order to power an active GPS antenna on that port. Output ports(J2-J32) would feature a 200 Ohm DC load to simulate an antenna DC current draw for any receiver connected to those ports.
  • If the failure in the primary antenna is resolved, the splitter will automatically switch back to the primary. The embedded switch has been designed so it can be controlled externally via a DB9 port or an external toggle switch that can override the internal automatic switch mechanism .

Antenna selection description

Powered hardware, the software began to calculate the signal strength of antenna 1and antenna 2,after comparing the intensity of the two input signals automatically select the high signal intensity of the antenna input. When two input antennas strength less than 34dB, according to the number of switches and the switching frequency of switching continues until the switching frequency greater than 140 times. When started with a good choice of antenna, the system continues to signal detection, when the signal strength is too low or the antenna failure, the automatic starting antenna selection logic. Holding the antenna 1 priority, it can delay the service life of the equipment.

Note:

Switching times: Each antenna switch once switches the number of plus 1 time.

Switching frequency : Switch the number of times less than ten times, then switch once every minute. Switching times greater than 10 times less than 140 times, every ten  minutes to switch once .
