GPS L1-L2 Repeater Systems

Supplier: Rojone

Rojone is pleased to release details of our GPS L1-L2 Repeater systems specifically designed to provide adequate GPS coverage of both L1 and L2 bands for aircraft and for use in surveying applications.


These systems are available in fixed installation solutions (in hangars, shelters and other internal buildings) as well as the fully self-contained emergency field-deployable kit supplied complete with antennas, repeater modules and all equipment in one compact module

Developed in conjunction with the Australian Defence Department, the emergency field-deployable kit has been in effective operation since 2006 at several RAAF bases in Australia.  Coverage is up to 15m at the maximum radiation direction, and the repeater kits are mounted and stored in a waterproof Mil Spec case with IP65 rating.

This portable GPS repeater system features;

  • High sensitivity receiver antenna, to track satellites with 5 deg elevation or above
  • High performance main RF amplifier with high rejection filters for both L1 and L2
  • High efficiency TX antenna with over 100 dB RF blocking to VHF & UHF radios and GSM mobile phone signals, plus well controlled radiation pattern to minimise the interference to the GPS receivers outside the shelter
  • Powered by batteries or 240V AC
  • Mounting kit for easy setup (less than 20 minutes) and pack up
  • Lightweight (38 kg) and rugged transport box
  • Self-protection function designed to prevent the damage caused by short circuits
  • Power supply will automatically function when the unit is switched on.  With low battery alarm function, a red LED will indicate limited battery life
  • Auto isolation detection circuit to speed up installation and maintain high performance
