A computer software program which plots radar video data on a display screen for viewing by a user in a format that emulates a real display. The radar video data the program plots on the display screen is either recorded radar video data generated by a missile radar video seeker or telemetered radar video data generated by the radar video seeker. The display screen display multiple radar scans of video data in the form of a graph or plot on the display screen.

A protocol converter that translates the ARINC-429 protocol output of an Inertial Navigation System to the National Marine Electronics Association 0183 protocol. The protocol converter includes an ARINC-429 interface board with cable and software operating in a computer with at least one serial communications port. The software includes a protocol conversion program which is capable of outputting the NMEA-0183 protocol to as many as four serial communications ports simultaneously.

Inertial navigation unit protocol converter

A computer program which plots radar video data generated by a seeker on a missile. The program allows a user to plot multiple scans of radar video data on a chart, which is obtained from a Data Worksheet. The chart displays one or more sets of radar video data scans and a detection gate plot for each radar video data scan. The program includes Zoom In, Zoom Out, Pan Left and Pan Right functions which allow the user to view and manipulate views of the data displayed by the chart.

Radar video data viewer

A PCM encoder which receives asynchronous serial data and incorporating the serial data and eight channels of analog data into a PCM data stream. The encoder includes a microprocessor which processes the serial data provided in eight bit digital words and the analog data which the microprocessor converts to twelve bit digital words. The encoder also has a programmable gate array which receives six bits of data during each transfer of data from the microprocessor to the gate array. The gate array for the PCM encoder also receives a Frame Sync, and then processes the data to provide a data stream containing NRZL data and Bi Phase data.

Computer software for testing the performance a Joint Advanced Missile Instrumentation Time-Space-Position Information Unit (JTU). The computer software is utilized for Functional, Acceptance and Qualification test of the JTU. The software has the capability of bench test the JTU and field testing the JTU to verify and document functionality of the JTU prior to use of the JTU in an operational environment.

An Auto Focus and Zoom Controller for controlling multiple cameras and their lens tracking a vehicle in flight at a test range. The Auto Focus and Zoom Controller controls camera lens functions including focus, focal length, and exposure settings, based upon information stored in a track file, in order to obtain optimal recordings of launch events at the test range.

Auto focus and zoom controller for controlling multiple cameras

A method for controlling multiple cameras and their lens tracking a vehicle in flight at a test range. The method controls camera lens functions including focus, focal length, and exposure settings, based upon information stored in a track file contained within an Auto Focus and Zoom Controller, in order to obtain optimal recordings of launch events at the test range.

A method for storing a crypto key and an associated checkword of the crypto key stored in a non-volatile memory within a micrcontroller and then providing the crypto key and associated checkword to an encryption device. The method next loads the crypto key and associated checkword into the encryption device.

The method is utilized for Functional, Acceptance and Qualification test of the Missile Time-Space-Position Information Unit. The method has the capability of testing the Missile Time-Space-Position Information Unit to verify and document functionality of the Missile Time-Space-Position Information Unit prior to use of the Missile Time-Space-Position Information Unit in an operational environment.

A method using a Non-Volatile Memory circuit which operates as an interface between a key loader and an encryption device in a missile's telemetry system. The method includes a step for storing a crypto key and an associated check word and a backup crypto key and check word in the EEPROM of a microcontroller, and a step for indicating the status of a load of the crypto key in the microcontroller as well as a step for indicating the status of an erase of the crypto key from the microcontroller. The method also includes a step for turning off the missile's transmitter when a key load occurs to prevents transmission of the crypto key and its corresponding check word. The method further includes a step for erasing the crypto key and its associated check word from an EEPROM within the microcontroller upon a missile launch.

Method which uses a non-volatile memory to store a crypto key and a check word for an encryption device

A Non-Volatile Memory circuit operating as an interface between a key loader and an encryption device. The Non-Volatile Memory circuit includes a microcontroller which stores a crypto key and checkword and a backup crypto key and checkword. The microcontroller is connected to the telemeter transmitter for a missile allowing the micrcontroller to turn off the transmitter during a key load which prevents transmission of the crypto key and checkword. When the microcontroller completes a load of the crypto key to the encryption device and upon a launch of the missile, software within the microcontroller erases the crypto key and checkword from an internal EEPROM. This prevents an enemy force from retrieving the crypto key and its corresponding checkword from the missile after launch.

Non-volatile memory for use with an encryption device

A monitoring apparatus which allows the user to monitor transmit and receive data of half duplex communications taking place over a full duplex RS-232 bus and also monitor full duplex communications on the RS-232 bus. The monitoring apparatus includes six switching transistors which are turned on and off depending on input voltage levels appearing at the transmit and receive lines input to the monitoring apparatus from the RS-232 bus. Turning on and off the switching transistors enables a computer, lap top or other device connected to the monitoring apparatus to receive and process data communications on the RS-232 bus.

A protocol converter for use on board an aircraft with space limitations which converts navigation data from one format to another format for use by the aircraft's moving map display. The navigation data is supplied by an aircraft inertial navigation unit to the protocol converter in the ARINC-429 protocol which converts the data to the NMEA-0183 protocol. The converted data is then supplied to a moving map display on board the aircraft. An interface board receives ARINC navigational data from the aircraft navigation unit and stores the data prior to its transfer to a digital computer. The computer reads the data stored in the interface board including a status word which indicates the validity of the data. A computer software program within the computer converts the ARINC-429 navigational data to NMEA-0183 protocol data. The NMEA-0183 protocol data is transmitted through an RS-232 serial port to the moving map display.
