iMAR Pipeline Surveying Explorer

iMAR launches iPSE "Pipeline Surveying Explorer" using Inertial Measurement System, Marker and Odometer Data

 With the iPSE - iMAR Pipeline Surveying Explorer a powerful processing tool is provided to pipeline maintenance and operator companies to calculate accurate position, attitude and heading of a pig (pipeline surveying vehicle) for pipeline surveying and maintenance tasks.

The iIPE uses as input information from the inertial measurement system (IMS) applied on the pig (like iPST-FMS or iPST-RQH), i.e. angular rates, acceleration and odometer information as well as external position aiding information (so-called markers). The result is a geometry file in WGS84 or ECEF containing the surveyed pipeline trajectory and pig's heading, roll, pitch, position, velocity and angular rates as well as acceleration, all time stamped in UTC84.

AutoDrop: Accurate Navigation for Swarm operated Sea Floor Shuttles

iMAR has joined the AutoDrop Development Consortium. The objective of the project is to develop a novel autonomous underwater vehicle that will significantly reduce the cost associated with deployment of sensors and data loggers to the seabed. The vehicle is equipped with sensors or loggers and is dropped into the ocean (e.g. seismic loggers). It descends rapidly under the influence of gravity, while autonomously navigating towards a pre-programmed destination on the seabed. After completion of data acquisition, the vehicle returns to a predefined location on the surface for easy retrieval. This vehicle for transportation of assorted equipment is the AutoDrop.

The program is partially funded by EU's FP7.

iMAR contributes in the part of navigation, path control and stabilization of the AutoDrop by hardware and software.

Advanced iNAV-FMS-E-DA Inertial Navigation System without any export restrictions

iMAR launches advanced iNAV-E-DA INS/GNSS System for LIDAR, Navigation and Guidance Applications

An advanced design of iMAR's wellknown fiber optic gyro based general purpose navigator iNAV-FMS is now available. It is fully form-fit-function compatible to iMAR's iNAV-RQH systems (ring laser gyro based with extended bias stability) and iMAR's iNAV-FJI-001 with high performance fiber optical gyros, but is not covered by any export restrictions. The internal fiber optic gyro is of class 0.75 deg/hr and true heading is determined by a dual antenna GPS for GNSS engine. So iNAV-FMS-E-DA provides heading at standstill as well as under motion, without the need of using north seeking class of gyros, which would be covered by export restrictions.

Key advantages of iNAV-FMS-E-DA are:

  • lower weight (8 kg) despite of additional features like optional integrated MIL-STD-1553B bus
  • MEMS based servo accelerometers of class 2 mg and and 0.1 deg/sqrt(hr) FOG
  • no export restrictions and no ITAR restrictions
  • Fully qualified to MIL-STD 810F, MIL-STD 461E, MIL-STD 704D; DO160E for 50 ms hold-over at power drops; usable for aircraft, train, ship, truck navigation etc.
  • no internal vibration isolators, therefore suitable for advanced laser scanning applications due to zero misalignment even under dynamic motion
  • integrated RTK GNSS receiver with 2 cm position accuracy (GPS / GLONASS / GALILEO)

Freitag, 20 Mai 2011 iVRU_FC

Vertical Reference Unit iVRU-Fx without external Aiding Requirements

New Algorithm for iVRU series available

A new EKF based algorithm is available for iMAR's iVRU product line, which provides a milestone in performance of unaided Vertical Reference Systems. The algorithm is available for new systems of iVRU series as well as for upgrade.

Standard vertical reference systems require magnetic information or GPS data (velocity) to determine the attitude of a moving vessel acording to the static plumb line. Where such aiding is not available, such systems align to the "dynmic plumb line" direction, which results from the superposition of the "static plumb line direction" and the motion induced acceleration (according to Newton's laws it cannot be distinguished between heavy mass  induced acceleration ["gravity"] and dynamic acceleration). 

The new EKF based iVRU algorithm uses some very general knowledge of airplane and ship motion to provide real attitide against "static plumb line" even if the vessel is under strong dynamic motion. Furthermore under dynamic motion it provides an estimation of vessel's velocity. 

The algorithm is suitable for mid perfrmance FOG based systems as well as for MEMS gyro based systems.

Further information:

iVRU for target drones, missile warning systems, ship stabilization etc.
