C-Band Beam Switching Stub Antenna

BSSA-4453-1 C-Band Beam Switching Stub Antenna (BSSA)

The C-Band “active” beam-switching stub antenna (BSSA-4453 series), when integrated into a Test Article (TA) as part of a Telemetry (TM) system, provides robust TM links to the Range Telemetry,...


TAS-311-1, Tracking Antenna System (TAS), is a compact light-weight S Band telemetry (TM) ground receiving station, comprising of RHCP flat panel antenna, tracking controller, RF receiver, and a dual-axis mechnical positioners all enclosed within a radome for environmental protection.

The TAS is designed to provide TM reception during flight tests of aircraft, helicopters and UAVs, at remote locations currently not covered by the test range infrastructure. The TAS also provides support for operational test and evaluation of ground vehicles and personnel, often as part of a training or war-game exercise. The unit is easily transported by air and ground vehicle in a ruggedized case, for deployment at remote locations.

The TAS operates using an external DC power source conforming to MIL-STD-704F. The TAS is also operable at remote locations with an external high capacity 24VDC battery. The TAS is rapidly configured through serial communications and GUI installed on an external computer.

The TAS provides autonomous search and acquisition of designated test articles, based on the assigned carrier frequency. The TAS provides the capability for seamless transition from acquisition to track, using one of three tracking modes, (i) RF signal tracking, (ii) test article GPS location (if available) tracking, and (iii) manual tracking by the user/operator. For multiple test articles with closely assigned frequencies, the TAS provides a sorted list of available targets and their directions, based on their received signal strength and quality. The user may select the preferred test article for continued autonomous tracking.

The TAC provides exceptional performance with low system noise figure and good gain over noise temperature (G/T) using modular sub-systems. The demodulated clock and data is available for storage on the external computer, network, or media. It also provides the option to view selected TM data on the external computer, when used with the optional TTC decommutation software. This option enables the user to view high priority data channels directly at the test site.

The TAS is designed for operation in harsh environments with direct exposure to solar radiation, rain, sand and dust, and fog.
