High Performance Low Weight / Small Size INS (RLG based)

The iPRENA-V is a light weight small-size high accurate advanced RLG based INS, being designed for aviation and used for defense applications. It is available in several performance classes. It consists of 3 high reliable airborne grade ring laser gyro axes and 3 servo accelerometer axes, integrated GNSS Receiver (GPS, GLONASS, GALILEO, BEIDOU; SBAS), wheel sensor interface and an advanced 42+ state Kalman filter based INS/GNSS loosly or tightly coupled data fusion.
The iPRENA-V is available in 3 different classes of performance (-MP, -HP, -UP).

A version iPRENA-M-H is furthermore available as MAPS / DRU replacement (compatible in enclosure, connectors and performance with "historical" DRU / MAPS modular azimuth position system, which became obsolescent some times ago by several vendors).

Features

• Applications: GNSS aided navigation, free inertial Navigation (air, land, sea, subsea), attitude heading reference (AHRS), surveying, UAV, AUV and RPV guidance & control
• Real-time data output: longitude, latitude, alttude / height, velocty, roll, pitch, yaw / heading, angular rates, acceleration, status, calibrated raw data INS/GNSS (for post-processing)
• Interfaces: RS485 (UART and HDLC / SDLC) Interfaces, CANaero / ARINC825 / CAN, ARINC429, Ethernet (TCP/IP and UDP), SYNC-I/Os
• Data Output rate up to 300 Hz (each data log separately adjustable)
• Measurement range +/-450 deg/s, +/-16 g
• Heading accuracy 0.2 ... 1 mil sec lat
  Attitude accuracy < 0.2 mil
  Position accuracy free inertial 0.2 ... 0.8 nm/hr
  Position accuracy GNSS aided < 1 m (rms) [S/A off]
  Position accuracy GNSS aided 0.02 m (rms) [RTK available]
• Bias over temperature 0.002...0.004 deg/h / 25 µg
  Noise / ARW 0.0012 ... 0.0035 deg/sqrt(hr) / 8 µg/sqrt(Hz)
  Bias stability (AV) < 0.001 °/hr, 10 µg @ const. temp.
• Integrated 42+ state tightly or loosly coupled data fusion
• Internally up to 32 GByte non-volatile memory for data storage
• Power Supply: 10...32 V DC, < 30 W
• Modular System architecture: customized applications can be integrated by iMAR easily (please contact our sales for details). So the iPRENA-V can provide arbitrary data and command protocols according to customer requirement, e.g. to substitute other navigation systems by iPRENA-V (e.g. for Form-Fit-Function replacements)
• EMI-EMC protection and qualification according to DO160G / MIL-STD-704F / MIL-STD-461G / MIL-STD-810G
