<li>Because PointPerfect uses a model instead of a dedicated base station, it is cheaper than many alternative correction services. However, the RTK Fix is not as accurate (3-6cm) as compared to getting corrections from a dedicated base station (2cm or better but depends on the baseline distance).</li>
3262
3252
<li>Because PointPerfect uses a model instead of a dedicated base station, convergence times (the time to get to RTK Fix) can vary widely. Expect to wait multiple minutes for an RTK Fix, as opposed to corrections from a dedicated that can provide an RTK Fix in seconds.</li>

<p>This service is commonly used with cellular hot spots. When this service is enabled, the device will attempt to connect to WiFi. If registration has been completed through SparkFun (see above), the device will be allowed to obtain NTRIP credentials. The NTRIP Client will be automatically turned on, and the device will quickly enter RTK Float, the RTK Fix states. Users report fast fix times with good accuracy.</p>

<p>In the above image we see the WiFi symbol indicating a high signal strength. The down arrow indicates the arrival of new data. The double cross hair indicates the device has an RTK Fix with a reported 5mm horizontal accuracy. 39 satellites are in view. The IP address of the device is shown. In the lower right corner the SNIP icon indicates the corrections source is NTRIP, and the page icon updates to indicate active logging. The <strong>A4D2</strong> indicates the device's Bluetooth MAC.</p>
<p>PointPerfect Flex RTCM/NTRIP service uses a standard NTRIP interface to obtain corrections. Once registered, to gain access to the PointPerfect system, the device must be given WiFi. The RTK device will automatically obtain <strong>credentials</strong>. These credentials will be copied into the NTRIP Client, and the NTRIP Client will be turned on. The device will then use WiFi (usually a cellular hot spot) to connect to the PointPerfect NTRIP Caster and begin providing the SparkFun RTK device with corrections. Within a few seconds, the device should change from RTK Float to RTK Fix.</p>

<p>When this service is enabled, the device will attempt to connect to WiFi. If registration has been completed through SparkFun (see above), the device will be issued L-Band specific keys and will obtain corrections over an extra signal broadcast by a geosynchronous satellite. The encrypted SPARTN packets are sent through the PointPerfectLibrary (PPL) and RTCM corrections are produced after ~60 seconds. The device will enter RTK Float, the RTK Fix states. Users report variable fix times with ok accuracy (not as good as RTCM service).</p>

<p>PointPerfect L-Band keys are valid for a maximum of 56 days. During that time, the RTK device can operate normally without the need to update keys. However, when the keys are set to expire in 28 days or less, the RTK device will attempt to log in to WiFi at each power on. If WiFi is not available, it will continue normal operation.</p>
<p>L-Band coverage is currently limited to North America and u-blox has announced L-Band North America service will be discontinued on December 31st, 2025.</p>
<p>All SparkFun RTK products can operate in RTK mode out-of-the-box using corrections from a local base or a RTCM provider (see <ahref="../correction_sources/">Correction Sources</a>). If you wish to use PointPerfect corrections, the device must be registered before it is allowed on the PointPerfect network. To facilitate this, please <ahref="https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/menu_pointperfect/#obtaining-the-device-id" target="_blank" rel="noopener">obtain your device ID</a> through the software interface and visit the registration page associated with your device:</p>
