XMA - Airborne Data Acquisition Units

Introduction:

 

XMA Flight Test Data Acquisition System

45 years of experience in flight test instrumentation and telemetry solutions have enabled Safran Data Systems to design and build technology that performs reliably in the most challenging environments and meet evolving needs in the industry. Their equipment is the first choice with customers worldwide.

With its compact and ruggedized design, the XMA series from Safran Data Systems is the ideal fit for remote data acquisition in those harsh and tight spaces found in aircraft. It is the perfect candidate for network telemetry applications and remote acquisitions, reducing the length of intrusive wires by acquiring data closer to the sensors. The XMA also allows data recording, data processing, GPS localization and data transmission. It has the smallest size/channel types ratio, and provides optimized module sets for a large number of data type acquisitions, all with state-of-the-art accuracy. Full status and health information of the unit is remotely available for live monitoring

Multiple XMA units can be networked, and their output recorded using a flight test data recorder such as the MDR, or broadcast using an airborne telemetry transmitter to a ground station.  The XMA OBP provides onboard processing that can be used to reduce the size of data budget, whilst the eZ Software used to configure, process, and decommutate.

 

Key Features:

 

- Harsh Environments:  -50°C / +105°C, waterproof, shocks, vibration, lightning, EMI/EMC
- INET Ready: UDP communication, IEEE1588 synchronization, SNMP
- Ultra Compact & Generic: Generic analog module, 2x3’’ / 51x76 mm, from 1 to 16 modules per stack
- Easy to Configure: eZ software suite, XML schema (MDL)
- High Data Rate Accuracy: 0.05% in extreme temperature range
- Multi-format Outputs: PCM Chapter 4, Chapter 7, Chapter 10, UDP, IENA, DAR

 

Configuration:

 

Comprising of either one of two core unit which consists of a power supply and PCU, acqusition modules are added to suit the requirements of the test. See diagram below.

 

XMA Core8 - Small to medium data acquisition unit

  • 1 Central Processing Unit
