MIL-STD Miniature GPS Sync Timecode Generator 6115G-8SA

The 6115G-8SA is a MIL-STD qualified miniature IRIG B Timecode Generator with a 12 channel GPS receiver and event trigger input. It generates three IRIG B122 timecode outputs, position and optional NMEA 0183 GGA and GSA sentences via RS-232 port.

This model meets the environmental requirements of an E-2C Aircraft.

The ITS Model 6115G-8SA is a MIL-STD miniature GPS Sync IRIG B Timecode Generator with optional NMEA messaging and provides IRIG B timecode outputs. The internal timecode generator is synchronized with UTC time derived from GPS. When a GPS signal is not available the unit will switch to an IRIG B reference input. If neither are available, it will automatically switch to an internal clock and continue generating output IRIG B signals.

Firstly, the 12 channel GPS receiver automatically acquires all in view satellites on power up. It locks the internal IRIG B timecode generator to the GPS time reference. If no GPS signal is present, the unit is locked to an applied IRIG B time reference (via time zone offset). The internal clock has a battery backup. Therefore, it maintains time during power interruptions.

Secondly, the 6115G-8SA has an asynchronous RS-232C port. It enables configuring of the unit as well as reading the time, event and location information. The output messages for time, location and events are individually controlled and may be set to OFF or AUTO. When set to AUTO messages are sent at one second intervals. A self-installing utility program for setting up the unit on Windows via a Graphical User Interface (GUI) is provided.

Thirdly, the 6115G-8SA is housed in an aluminium enclosure.  Designed to meet shock, vibration and EMI requirements of Defence Aircraft. With all controls, connectors and indicators on the front panel. It is 19cm long x 10.80cm wide and 5.08cm high.
