KAM/TCG/103 accepts time from three sources: a digital IRIG-B stream (RS-422 or TTL), its own onboard GPS receiver, or from ARINC-429 time labels.
- Synchronizes to digital IRIG-B or GPS
- Loads time from specific ARINC-429 labels
- 1 μs time resolution
- Less than three parts per million drift when acting as a generator
- Time is maintained from an external battery during power-off
- GPS navigation information is available
- Secondary time source input
- System synchronization
- Parameter time tagging
- Global positioning
KAM/TCG/103 Combined GPS, IRIG and ARINC-429 Input Module
The KAM/TCG/103 accepts time from three sources: a digital IRIG-B stream (RS-422 or TTL), its own onboard GPS receiver, or from ARINC-429 time labels (octal labels 260 and 150). It can be synchronized to the digital IRIG-B stream or GPS receiver. However, it does not synchronize its clock with ARINC-429 as there is too much clock jitter. The received time is written to an internal timer and to a real-time clock that maintains time during power-off (when an external battery is connected). The time can be used for the synchronization of a distributed Acra KAM-500 data acquisition system. The module generates digital IRIG-B outputs to allow external devices to synchronize with the Acra KAM-500 system.
The module contains an IRIG-B, GPS NMEA and ARINC-429 decoder that decodes incoming signals. The GPS decoder also makes navigation data such as position, altitude, velocity, and heading available as individual parameters.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
