SPARS Plus++

---

Sensor Positioning And Readback System (SPARS) Sensor Buffer Plus++

Standard Key capabilities

• Standalone system generating all internal clocks and triggers from GPS signals – generates own IRIG-B
• Accepts four (4) serial streams (+5VDC to +28 VDC) for azimuth angle position, elevation angle position, range, and auxiliary data
• Provides one serial range acquisition data
• Outputs 40 Hz read pulse, 29 shift pulse streams with a programmable period, and two other programmable pulse streams.   
• Provides three (3) analog signals to drive the azimuth and elevation servos and ranger
• Provides 24-bit digital input/output signals for general purpose
• Provides eight (8) channels of optically isolated relay input and eight (8) of electromechanical relay output
• Sends asynchronous serial stream of antenna pedestal azimuth and elevation data, range and auxiliary data to the Source Integration Server (SIS)
• Receives asynchronous serial stream of azimuth, elevation and range designation data from the SIS
• All parts are Commercial Of The Shelf (COTS)
• DISA STIGs and Nessus Scan Compliant

Added++ capabilities

• Provides 8-channels of analog to digital converters for the strip-chart display and recorder – digitally record strip-chart
• Reads mis-level amplitude while commanding 360 deg antenna rotation
• Antenna growler – pitch and amplitude of the sound is dependent on the speed of the antenna motion
• Send and receive PMRF iNet Message 37 data to/from the SIS with optional Cisco firewall
• Voice status warning – synthesized voice generated to warn operators of critical warning

Plus++ features

• Autodiagnostic software – self-diagnostic software that automatically isolates hardware failure to board level
• Sun tracker – points to the sun for solar calibration
• Satellite propagation – reads three/two-line element (TLE) and propagates the ephemeris for antenna pointing
• Pre-flight nominal – load ballistic and non-ballistic pre-flight nominals in RAE and XYZ format and use it as internal designation source
• Save State-vectors – cut state vectors from its track and use it as position designation 
• Polar antenna display – antenna pedestal position plot in polar coordinate
• Graphical plot of vector comparison – compare multiple designation sources with pedestal position

Optional capabilities

• Video capture to display and digitally record antenna mounted camera
• Full/all range display of emitters in pulse-shape and water-fall scrolling intensity plot
• Data capture and recording of the Sum/Az/El receive channels with pulse-shape and Range-Time-Intensity plot

On-site support & warranty

• On-site installation and testing
• 1-year warranty on hardware parts
• Monthly operating system and software updates to meet cybersecurity compliance for 1-year
