GNSS-Aided Inertial Navigation System

The INS-T-306 is the advanced module that combines GPS L1/L2, GLONASS, BDS navigation and a high-performance strap-down system. It is capable of determining position, velocity and absolute orientation (heading, pitch and roll) for any device on which it is mounted. It aims at facilitating motionless and dynamic applications that need high accuracy, such as vessels, ships, helicopters, unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs).

The INS-T-306 utilizes an advanced GNSS receiver, barometer, magnetometers, MEMS accelerometers and gyroscopes to provide accurate position, velocity, heading, pitch and roll of the device under measure. Besides GPS L1/L2, GLONASS and BDS, the unit supports differential GPS and real-time kinematic (RTK). It is able to integrate into LiDAR (Velodyne, RIEGL and Faro brands). The on-board sensor fusion filter, navigation and guidance algorithms, and calibration software inside all make INS-T-306 a commercially exportable GNSS-aided inertial navigation system.

$15,000? Well, that's out of DIY by a far margin. What component(s) costs so much?

Comment by Hugues on July 6, 2017 at 4:19am

the component that cost that much ? I think it is called "industry agonizing dinosaur brand name" unable to face hardware that once was exclusive to them becoming a utility at quasi zero price, accessible to the general public (and with public technical ability and education increasing at levels they never could forecast). Added value is not anymore in hardware but in customized (per job) added value services. Those who don't understand that will die and disappear from the market soon.

Maybe a more restrictive selection of forum entries would help...

There is a certain degree of "you get what you pay for" in some products.  Sure, 9 DOF IMUs are dirt cheap these days but they either don't have any sensor fusion software to go with them or the software is crap.  I wasted several months trying to calibrate a 3-axis magnetometer only to discover that the vendor's calibration algorithm was totally wrong.  This product has more involved sensor fusion so it can command a higher price tag.  $15k does seem expensive but I'm guessing that they don't envision selling too many so they have to offset their development and operating costs.

friends, they have right to demand whatever price they like. any flight controller hardware is useless unless it has a significant software support. they can only be achieved when a project is open source like pixhawk and APM and drone code. in open source even an ordinary person (no engg degree etc,) can contribute something very significant.

It is a pro-grade device designed to sell alongside units from companies like Lockheed-Martin, I would guess. Even though it is not remotely DIY it is still more interesting to read about this than some of the inane general interest things that have been appearing here that seem like Google AI blogging experiments.

It is completely in-line with his market, which is definitely not DIY. A complete basic Lidar system for drone starts around 100.000 € and goes quickly up. It is roughly a Velodyne rotating laser (8.000 €) + GNSS + INS + acquisition part. So 15.000 for GPS+INS is not shocking at all. If you target the survey market.

If the gyro specs ( 1 deg/hr bias instability ) was true, the price is not high. however, it's a little weird for a not well-known ins manufacturer. usually these specs is for tactical grade ins and almost all of them with fog based gyros.

Thanks everyone for the input.

Inertial Navigation System (INS) could be classified in terms of application scenarios and industries, thus, the price could range from a few hundred dollars to far higher. This INS-T-306 is more suitable for high precision uses. For example, surveying, aerial-related drones, mapping vehicles, automatic driving systems. As @ Pascal P @Rafael Mendy shared, it is quite industry-specific.

If possible, take a look at the spec, click here and compare it with other similar IMU+GNSS combined systems. For some of our customers, who have tested this unit for quite a time, they found it very competitive, both for the cost and feature. One key advantage of this INS is the Kalman Filter Fusion Algorithm (IMU+GNSS). Users can get more accurate attitude details, whether it is real-time or post-processing. In short, it is the embedded Kalman Filter based sensor fusion algorithms. Any comments, feel free to let us know.

Do you provide an SDK with this allowing us to hook in our own sensors (i.e. positioning from our own SLAM systems)?
