The Portable Jamming System (PJS), is a portable GPS jammer developed for companies to test their commercial GPS products (antennas, receivers, etc.). PJS utilizes a software defined arbitrary waveform generator which allows for rapid development and insertion of current and new threat waveforms along with an analog noise generator providing true Gaussian noise.

The system is equipped with a real-time spectrum analyzer for power monitoring and signal verification. The system is capable of full wireless remote operation allowing for placement in areas that require personnel to evacuate during operations. The system is available in 100 and 300 watt output power models (TMC-PJS-100 and TMC-PJS-300, respectively).

The system is housed in ruggedized rack-mount transit cases providing protection from shock, vibration, and the environment. By using multiple systems GPS EC threat laydowns can be created using the latest signal techniques and variable power levels with an array of antenna types.

1 – High-Power Amplifiers (HPAs)
The PJS contains a dual HPA configuration for independent transmission of two frequencies through two channels.  Power output can built to suit, ranging from 100 to 500 watts.

2 – Wireless Transceiver 
A programmable modem for remote control and monitoring of the PJS. Multiple PJS can be networked and automated together for broad area coverage. The modem is also tied to a watchdog timer for remote recovery during operation.

3 – Analog Noise Generator (ANG)
A 1RU system that generates a true Gaussi- an noise signal with a bandwidth up to 30 MHz.

4 – TMC Advanced Signal Source (TASS)
A rack-mounted, 3RU, industrial grade controller that generates digitally modulated signals, including BPSK, sawtooth, and CW.

5 – Patch Panel Interface
The system is enclosed in, rugged weather-proof cases with patch panel interfaces, allowing the system to operate in remote, outdoor locations.
