iPRENA-II...IV: Precision Navigation for Defense Applications (0.3 mil sec lat, RLG, ITAR-free)
High Performance Low Weight INS (RLG based, no ITAR)
The iPRENA-II...-IV family is a series of light weight, small-size, high accurate INS/GNSS systems, consisting 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.
Three performance classes down to 0.3 mrad sec lat true north gyro compassing capability are available.
With iPRENA-M-II...-IV also a gun-fire hardened system is available.
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: RS422 (UART and HDLC / SDLC) Interfaces, CANaero / ARINC825 / CAN, ARINC429, Ethernet (TCP/IP and UDP), SYNC-I/Os
Data Output rate up to 400 Hz (each data log separately adjustable)
Measurement range +/-395 deg/s, +/-20 g (option: +/- 40 g)
Heading accuracy with Gyro Compassing (pure inertial): 0.3 mil / 1.0 mil / 1.5 mil sec lat Attitude accuracy < 0.1 mil Position accuracy free inertial < 0.5 nm/hr / < 1 nm/hr / 1.5 nm/hr (after > 12 hr GNSS aiding with sufficient motion: down to 1 n/m / 24 hr) Position accuracy GNSS aided < 2 m (rms) [S/A off] Position accuracy GNSS aided 0.02 m (rms) [RTK available]
Bias over temperature 0.002 ... 0.007 deg/h / 50 ... 100 µg Noise / ARW 0.0016 ... 0.005 deg/sqrt(hr) / 12 µg/sqrt(Hz) Bias stability (AV) < 0.001 °/hr, 12 µg @ const. temp. See datasheet for further accuracy classes.Integrated 42+ state tightly or loosly coupled data fusion
internal GNSS receiver, up to all frequencies / all constellation GPS+GLONASS+Beidou+GALILEO; RTK or/and SAASM / M-Code as option
Internally up to 128 GByte non-volatile memory for data storage
extreme high reliability: IMU MTBF (field demonstrated in transportation aircraft environment): 120'000 hrs
Power Supply: 10...32 V DC, < 30 W
Modular System architecture: customized applications can be integrated by iMAR easily (please contact our sales department for details). So the iPRENA can provide arbitrary data and command protocols according to customer requirement, e.g. to substitute other navigation systems by iPRENA (e.g. for Form-Fit-Function replacements)
Gun-fire hardened version available: iPRENA-M-II /-III / -IV
EMI-EMC protection and qualification according to DO160G / MIL-STD-704F / MIL-STD-461G / MIL-STD-810G
iPRENA-(M)-II / -III / -IV are not ITAR controlled and handled as dual-use equipment for export control.
