Feature bd992-ins

The bd992-ins is a dual-antenna receiver that delivers centimeter accurate positions and precise heading. Heading derived from dual-antenna GNSS measurements helps overcome issues such as difficulty determining where the antenna is positioned relative to the vehicle and object of interest.

The bd992-ins dual-antenna GNSS system is a single board solution for precise position and heading. Heading derived from dual-antenna GNSS measurements help overcome issues typically seen in single antenna GNSS systems such as difficulty determining where the antenna is positioned relative to the vehicle and object of interest or drifting external sensors caused by static.

GNSS Boards/ GNSS +Communication Boards

The latest centimeter-level positioning technology for system integrators. Trimble GPS/GNSS receivers are designed to allow easy incorporation into specialized or custom hardware solutions.

Trimble GPS/GNSS receiver modules harness the widest range of GPS L1/L2/L5 and GLONASS L1/L2 signals in easy-to-integrate modules that provide fast Real-Time Kinematic (RTK) initialization with proven low-elevation tracking. Decimeter positioning with OmniSTAR XP/HP support is also available.

bd992-ins + Communication boards include also Bluetooth & Wi-Fi or internal UHF modem. Trimble’s quality GPS/GNSS OEM receiver modules currently include the BD910, BD920, BD930, BD940, BD970, BD982, BD990, BD992, BD935 INS, BD940 INS, MB-One, MB-Two, BD920-W3G and the BD930-UHF.

GNSS receivers enclosures are multi-channel, multi-frequency rugged GNSS receivers allowing OEMs and System Integrators to rapidly integrate centimeter level positioning and precise heading into their application by using a dual antenna connection or by using an INS sensor.

Trimble/Applanix line of GNSS OEM Sensors Enclosures include the Trimble BX940, Trimble BX992, Trimble BX982, Trimble BX935-INS, Trimble ABX-Two and Applanix POS AVX 210.

The Trimble – Applanix AP series include embedded GNSS-Inertial OEM boards plus Inertial Measurement Units (IMU) for continuous mobile positioning in poor signal environments and high-accuracy direct geo referencing of imaging sensors. Product line includes the Trimble AP10, AP15, AP20, AP40, AP50, AP60 and the Applanix APX-15UAV.

All Trimble Multi GNSS antennas conform to strict standards of consistency and performance to deliver the best possible tracking to support centimeter level accuracy on aerial, land and marine applications. Unique antenna designs provide the flexibility to reach a wide range of operational goals.

The broad product offering include the AV28, AV33, AV34, AV37, AV59, LV59, AG25, GA810, the Zephyr antennas series, the Bulkhead and the bullet GG antennas and more.

GNSS technology has been widely used in the field of surveys and mapping. According to Abidin this is because bd992-ins can be used regardless of time, is not affected by the topography of the survey area, and provides accuracy with a wide spectrum.

GNSS technology also has several disadvantages, one of which is price. The tool used to implement GNSS technology has a high price, for example is the geodetic type which has prices ranging from hundreds of millions of rupiah. The last few years have found low-cost GNSS. which has a cheaper price. To find out the quality of low-cost GNSS a test was carried out. In this study a low-cost GN70 Oem Board was tested.

This study focuses on testing accuracy and precision. The method used for testing is RTK, and Static for data as a reference. RTK data acquisition uses the NTRIP method with CORS Surabaya as the base. There are 3 test locations in this study. The first is in BM01ITS or “bits”. Both the ITS Stadium or “bstd”, and third Sakura Park or “bskr”.

Horizontal and vertical deviation standards on the K706 OEM board has better quality than Topcon HiperPro. This is evidenced by the standard deviation of the K706 superior in 4 research points, while HiperPro only excels at two research points. Horizontal RMSE both devices have the same quality.

This is evidenced by the RMSE of the K706 superior in 3 research points, and HiperPro excels in 3 research points. For vertical RMSE, the K706 is better than HiperPro. This is evidenced by the standard deviation of the K706 superior in 5 research points, while HiperPro only excels at one research point.

RTK GNSS Receivers

Some of you may think that I should include “consumer” GNSS chipset designers like GlobalLocate/Broadcomm, SiRF/CSR, u-blox, NVS Technologies, etc. While some of the engineers at consumer GNSS chip companies clearly have the knowledge (and experience in some cases) of RTK design, none of these chipsets are integrated into commercial RTK products.

Yes, I know some of you have “made RTK work” with consumer GNSS chipsets, and I think that speaks volumes about where RTK capability will end up, but it’s not quite there yet with respect to a reliable commercial implementation.

GNSS chipsets, the multi-constellation, multi-frequency RTK GNSS receiver landscape is changing quickly, even before the deployment of the new L5 signal and Galileo as I’ve written about previously (Why the Price of Precision Receivers Will Drop).

This is because of the proliferation of RTK GNSS receiver “boards” such as the Trimble BD series, Novatel OEM series, Hemisphere GNSS P series, and Septentrio AsteRx series. System integrators like Altus, Geneq, CHCNav, Stonex, FOIF, Carlson, etc., are scooping up these proven receiver boards and designing their own systems around them.

There are more RTK GNSS system integrators in China than any other geographic region in the world. It makes sense because the Chinese market for RTK GNSS receivers is larger (much larger) than any other market in the world.

Even though you don’t see many Chinese-made RTK GNSS receivers sold in North America (you do see them sold in Africa, Europe and South America), they sell a huge number of them within China. I would even go as far as to say that the North American market is likely considered a “leftover” market since the North American RTK GNSS receiver sales volumes are so low in comparison.

In other words, North America is such a small market for RTK GNSS receivers, it’s not worth the marketing/selling effort it requires. That said, some companies, like CHCNav, are ramping up their marketing and selling efforts in North America.
