ABOUT
IPOZ GIPSI® Inertial Sled™ is a land survey instrument that utilizes Inertial Navigation technology. It is a high performance positioning tool with multiple applications, and in particular where GPS is not optimal.
The IPOZ GIPSI® Inertial Sled™ has the same accuracy after post-processing as RTK GPS and is lightweight and easy to use, a GPS-trained operator will already have all the background knowledge necessary for its operation including; range and bearing to target, load control waypoints and predetermined positions, record fix, position update, optional map backgrounds and more.
The Sled when carried by two people, provides a stable platform for the inertial navigation sensor to provide precise real-time and post processed results.
By design the IPOZ GIPSI® Inertial Sled™ is rain proof and can operate in most outdoors situations from -20c to +50C. The total weight including the sled is less than 70 lbs.
GIPSI Inertial Sled is perfect for
Subterranean Mapping - Tunnels, Sewer Systems, etc.
Surveying & Mapping in GPS Challenged Environments
Oil and Gas Seismic Exploration Surveying
THE IPOZ DIFFERENCE
+ REAL TIME ACCURACY
- 3D position: 0.3m per km between Control Points
- Heading: 0.05 degree
- Pitch and Roll: 0.02 degree
- Post-Processed Accuracy: Horizontal Position: 0.20m average Vertical Position: 0.20m average
- Recommended distance between Updates to Control Positions: < 3 km or 2 miles (linear)
+ INPUTS
- 3D position: can be input for Alignment or to Update position via binary files
- Navigation is computed internally at high rate using motions sensed by the INS itself
- All Inputs controlled by IPOZ survey software
- Input files can be created by e.g. GPSeismic™ and other proprietary software
+ OUTPUTS
- 3D positions are recorded in a Windows CE™ Handheld Computer
- Output files can then be processed on a PC by IPOZ or other off-the-shelf survey software, to create maps and Industry Standard formats (ASCII, SEGP1, DXF, DWG, SHAPE…)
+ IMU SPECS
- Vibration: Mil-Prf-71185
- Shock: Mil-Prf-71185
- Power Mil-Std-1275A,
- Power consumption: <25W data-preserve-html-node="true"
- Operation temp: -54C +71C
- MTBF >20,000h
+ PRODUCTIVITY
The results of comparison surveys show that the accuracy of the 3D positions recorded with IPOZ GIPSI® Inertial Sleds™ are similar to the best RTK GPS surveys on average, and therefore more than adequate for Oil and Gas exploration (seismic exploration), Forestry and many applications where a Land Surveyor is needed. The difference with theodolite surveys is its remarkable velocity: IPOZ GIPSI® Inertial Sleds™ can do the job at 4 to 5 times the productivity of conventional survey methods with half the team (crews of 2 or 3 men instead of 5 to 6 in theodolite crews, including brush and tree cutters).
+ ENVIRONMENTAL
The IPOZ GIPSI® Sled™ is an autonomous instrument, it doesn’t require line-of-sight or radio signals to operate. In forested environments this means that the surveyor does not have to cut any vegetation to survey even the straightest lines; the operator simply walks around trees and bushes, and places bio-degradable survey markers exactly in the position intended (preplot), but without any major environmental impact. With a month’s passing there is no indication that a survey took place and nature will have regained its rights. In contrast, other survey methods such as theodolite surveys require heavy cutting of vegetation in extremely straight lines that remain visible for years, and sometimes, start a process of erosion that is dramatic to the local area habitats and inhabitants.
