Using the integrated RTK algorithm to transmit data via DMB or LTE
Processing the received GNSS correction data
Centimeter-level accuracy
On the 12th, u-blox announced the results of its collaboration with Munhwa Broadcasting Corporation (MBC). MBC showcased the "MRP-2000," an ultra-compact L1/L2 multiband real-time kinematic (RTK) device equipped with the u-blox ZED-F9P high-precision GNSS module. This product is Korea's first centimeter-level RTK receiver that integrates a GNSS RTK receiver and the ability to receive GNSS correction services.

High-precision GNSS receivers require multiband satellite signal reception and GNSS correction data to deliver centimeter-level positioning accuracy. Multiband receivers not only reduce positioning errors that occur when satellite signals pass through the ionosphere, but also significantly reduce the time it takes for the receiver to determine a precise position. The ZED-F9P utilizes integrated RTK algorithms to process GNSS correction data received via DMB or LTE, enabling centimeter-level accuracy.

The MRP-2000, developed by MBC this time, is an ultra-small, ultra-low-power product weighing just 50g, providing centimeter-level positioning accuracy in a wide range of industries such as autonomous vehicles, drones, and exploration equipment. In particular, GNSS correction data generated through the reference station infrastructure built by MBC across the country is provided using the DMB data channel, and in DMB shadow areas, it is provided using the LTE network.

The u-blox ZED-F9P GNSS receiver featured in the MRP-2000 keeps the solution's cost, size, and power consumption to a minimum. With the latest multi-band RTK algorithms integrated into u-blox' chips, MBC has achieved centimeter-level positioning without the need for additional hardware or third-party RTK libraries.

“The integration of u-blox’s ZED-F9P, a mass-market RTK receiver, into MBC’s MRP-2000 product provides an opportunity to introduce u-blox’s advanced high-precision positioning technology to the market,” said Son Kwang-soo, Country Manager of u-blox Korea. “Combined with MBC’s existing DMB channel, the MRP-2000 solution will provide enhanced correction services to vehicles and industrial devices nationwide.”

He added, "We are very pleased that this collaboration will enable MBC to dramatically reduce the cost of ownership of centimeter-level positioning technology."

“We were able to develop the MRP-2000 through collaboration with u-blox,” said Seungho Lee, team leader of the MBC Technology Information Business Team. “This product is an integrated positioning solution that can use RTK data over an LTE network even in areas where DMB reception is dark.”

He added, "This will allow users to obtain centimeter-level high-precision location information throughout South Korea, and this will be a groundbreaking solution that can reduce the price of RTK terminals, which currently cost tens of millions of won in the existing market, by more than half."
