SPC’s Command Transmitter Systems (CTS) provides remote control and flight termination functions through a fully-redundant self-contained solid-state system, comprised of the following:
The high-power amplifier (HPA) is solid-state, dependable, and cool running, allowing continuous 1-kW output power at temperatures from 0 to 50 degrees Celsius, and from sea level to 30,000 feet AMSL. The CTS is MIL-STD-461C qualified and designed to military standards for high MTBF and continuous 24-hour-per-day operation.
State-of-the-art CMOS micro-controllers provide full fault detection and reporting. High-power ferrite isolators allow full-power operation with antenna VSWRs up to 2:1. As an optional feature, each HPA sub-system is provided with an RF switch matrix that allows real-time replacement of HPA units. External modulation inputs may be used to modulate the transmitters with externally-generated tones from 10 Hz to 100 kHz.
The system can be switched automatically or manually between transmitters. Automatic switching to the redudant system is completed in less than 5 ms upon detection of an internal fault or at preset RF power thresholds.
The system is mounted in two standard 60" racks for easy installation in mobile platforms. The roller-bearing, tiltable rack slides allow easy access within the chassis for low MTTR. CTS generally ships with front panel button operation for broadcast frequency and tones.
Add-on options are available from SPC for remote control features. For more information on an integrated control system, see SPC's Flight Termination System
