## Article

Original : <https://esprtk.com/shop-esprtk-firmware-3xx/> RTK-capable receivers require precisely calibrated antennas to process signals transmitted by the GNSS satellites. The process for achieving centimeter-level position accuracy in GNSS involves a complex algorithm known as real time kinematic (RTK) processing. In addition, they must receive and process corrections data from a ground network of GNSS receivers. These factors made traditional RTK-capable receivers costly (in excess of $5000 or even $10,000 ) and bulky, making them unsuitable for cost- and size-sensitive applications. Recently, GNSS equipment manufacturers have started advertising inexpensive (less than $500) and compact RTK-capable receivers. Some prominent names:

> - Hemisphere- Eclipse P307 (L1/L2).
>
> - NVS Technologies- NV08C-RTK (L1).
>
> - Swift ? Piksi Multi (L1/L2).
>
> - u-blox -NEO-M8P (L1).
>
> - Skytraq -S2525F8 (L1).
>
> Ethernet module support is W5XX (W5500 (100Mbps) -W5100-W5200) and ENC28J60 (10Mbps) , communicate to ESPrtk via SPI port to access internet.
