<p>To get millimeter accuracy we need to provide the RTK unit with correction values. Corrections, often called RTCM, help the RTK unit refine its position calculations. RTCM (Radio Technical Commission for Maritime Services) can be obtained from a variety of sources but they fall into three buckets: Commercial, Public, and Civilian Reference Stations.</p>

<p>See <ahref="../correction_sources/">Corrections Sources</a> for a breakdown of the options and the pros and cons of each. For this quickstart, we'll be showing two examples: using PointPerfect for $8 a month (a little less accurate but nation-wide coverage) and PointOne Nav for $50 a month (maximum accuracy, gaps in the coverage area).</p>
<p>One of the great features of the RTK Torch is that it has the ability to get corrections from PointPerfect over WiFi. No need for NTRIP credentials! <ahref="https://www.sparkfun.com/rtk_torch_registration" target="_blank" rel="noopener">Contact SparkFun</a> with your device ID, pay a small monthly fee of $8 per month (as of this writing) and your device will obtain credentials and start receiving corrections anywhere there is coverage.</p>

See the <ahref="https://www.u-blox.com/en/pointperfect-service-coverage" target="_blank" rel="noopener">coverage map</a> for specifics; the RTK Torch is compatible with any area that has <em>IP Coverage</em> (it is not compatible with L-Band coverage).</p>

<p>It is important that you set your Geographic Region correctly, via the menu or web config page, as this determines both the IP correction distribution topic and the L-Band frequency (on L-Band-capable products). Sadly, u-blox are suspending their EU L-Band service on March 10th 2025. L-Band coverage will only be available in the contiguous USA from that date.</p>
<p>After the reboot, the device will connect to WiFi, obtain keys, and begin applying corrections. Assuming you are outside, after a few minutes of receiving PointPerfect corrections to the device, connect to the RTK Torch over SW Maps (or other) and the device will enter RTK Float, then RTK Fix (usually under 3 minutes). You can now take positional readings with millimeter accuracy!</p>
