Remote Control Target System Anti-Jamming Technology

30 March 2021

GENERAL DESCRIPTION OF NEED

The targets flight is looking for a product that will interface with the current target GPS instrumentation that will allow our targets to receive GPS data, while operating in a GPS denied test environment.

Key Performance Parameters (KPPs)

The product must enable; 1) remote target operation in test environments using one or more GPS jamming devices, 2) ability of target assets to receive L1 (1575.42 MHz) and/or L2 (1227.6 MHz) frequencies for GPS operations.

The anti-jamming equipment will be installed on target assets that operate on either land or water ranges. The land ranges are typically compacted clay and sand/dirt mixture. The equipment should be suitable for use in sandy and dusty environments. The maritime targets operate at high speeds in the water ranges and the equipment should be suitable for use in marine applications where the equipment will be exposed to splashing. In both land and water applications, the equipment should be suitable against shock and vibration.

The interference rejection shall be at least 25 dB, 40 dB or more is preferential. The low noise amplifier gain should be at least 20 dB.

For connection to the remote control and tracking system, the anti-jamming equipment shall interface with the existing antenna with little or no modifications. The product can be used to replace the current GPS antenna. Power is typically available on the targets and anti-jamming equipment can make use of available power. Some modifications may be necessary to access the target’s power source.
