Harxon Smart Antenna Will Be Shown on EIMA 2022

Harxon smart antennas uniquely combine the most up-to-date GNSS technology with leading-edge receivers in robust and compact enclosures for an easy-to-integrate solution. Whether you need GNSS high-precision positioning, differential data transmission or correction services for enhanced accuracy and robustness, the smart antennas are designed to scale with your growing needs.

Of the multiple robust capacities, Terrain Compensation Function and STANDALONE Function play an important part in high-precision positioning. Let’s take a look at how the two functions work.

1. Terrain Compensation Function

The antenna is usually installed on the top of the machinery, and the output coordinates are its own position coordinates. However, the position coordinates of the bottom of the machinery are actually of more concern. The antenna shares the same latitude and longitude coordinates as its projected position on the ground, which is the reference point of the machinery position. When the machinery is running on the slope, there will be deviation between the position of the antenna projected to the ground and the reference point. The three-dimensional attitude angle (pitch, roll, azimuth) can be measured according to the built-in IMU sensor of the smart antenna. Combined with the height of the antenna from the ground, the ground projection coordinates can be adaptively compensated and real position of the reference point can be obtained. In this way, the problem of trajectory offset in complex terrain can be solved.

2. STANDALONE Function

STANDALONE makes full use of pseudorange, carrier, Doppler and other observational value information, it can eliminate errors affecting positioning accuracy such as satellite orbit, clock error, ionosphere and troposphere through model and parameter estimation. It maintains relative positioning with centimeter-level accuracy relative to the starting point for a certain period of time without the support of any external precision data. For applications that require high-precision pass-to-pass positioning like agricultural machinery, UAVs, intelligent robots etc., STANDALONE function can completely replace RTK, PPP and other technologies. There’s no need of equipment to receive differential data or precision orbital clock data, which greatly reduces cost and complexity. STANDALONE function can maintain 5~20cm positioning accuracy for up to half an hour in horizontal orientation, and maintain 30cm positioning accuracy within for up to an hour.

We’re Exhibiting!

Harxon will be attending the upcoming EIMA International 2022 on November 9-13 in Bologna, Italy. In this international agricultural and gardening machinery exhibition, Harxon will display its smart antenna series, auto-steering system and GNSS receiver. Look forward to reconnecting with our international partners and see the old and new faces in person. Meet our expert team at Booth #B24 in Hall 35.
