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.
Features
- 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
Applications
- System synchronization
- Parameter time tagging
- Global positioning
The KAM/CHS/13U is a thirteen user-slot Acra KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
The NET/SWI/101 is an 8-port airborne Ethernet switch designed for operating in harsh environments. Each port is configurable for 10BaseT, 100BaseTX, and 1000BaseT link speeds or auto-negotiate over copper wiring, supporting straight-through or cross-over cables.
DAS Studio 3 software allows you to configure DAUs, network switches, recorders & ground stations in an integrated environment.
The RFE/AEG/001 is a robust, rigorously tested, and environmentally sealed unit suitable for a wide variety of GPS applications. It is ideal for marine or airborne navigation installations requiring maximum security and durability.
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.
