<p><em>PointPerfect Flex</em> (previously known simply as <em>PointPerfect</em>) is just one service offered by u-blox/ThingStream. Other services (announced but not yet launched) are <em>PointPerfect Live</em> and <em>PointPerfect Global</em>. For the purposes of this article we will refer to <em>PointPerfect Flex</em> as <em>PointPerfect</em>.</p>

<p>PointPerfect corrections are obtained by two methods:</p>

<ul>
3240
-
<li><strong>IP</strong>: Corrections are transmitted over the internet. The RTK device will need access to a WiFi (or optionally an Ethernet/Cellular network on the RTK EVK). For WiFi, this is most commonly a hotspot on a cell phone so this delivery method is generally most common for areas with cellular and/or other WiFi coverage.</li>
3241
-
<li><strong>L-Band</strong>: Corrections are transmitted from a geosynchronous satellite. Coverage is limited to the US contiguous 48 states. This delivery method requires special equipment thus this method is only compatible with the the <ahref="https://www.sparkfun.com/products/24342" target="_blank" rel="noopener">RTK EVK</a> and <ahref="https://www.sparkfun.com/sparkpnt-rtk-facet-mosaic-l-band.html" target="_blank" rel="noopener">RTK Facet mosaic</a>. No cellular or internet connection is required.<ul>

<li>Sadly, u-blox is suspending the North American L-Band service on December 31st, 2025. A global L-Band service has been announced but with no set availability date at this time.</li>
<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>Once registered, to gain access to the PointPerfect L-Band system, the device must be given WiFi. The RTK device will automatically obtain <strong>keys</strong>. These keys allow the decryption of L-Band based corrections. </p>
<p>On devices that have a display, upon successful reception and decryption of PointPerfect corrections delivered over L-Band, the satellite dish icon will increase to a three-pronged icon. As the unit's fix increases the cross-hair will indicate a basic 3D solution, a double blinking cross-hair will indicate a floating RTK solution, and a solid double cross-hair will indicate a fixed RTK solution.</p>
<p>This service has been discontinued by PointPerfect and is still available for legacy devices. It is recommended to use PointPerfect Flex RTCM/NTRIP for a better experience. 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 MQTT specific keys and will obtain corrections over an MQTT client. 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>The u-blox PointPerfect Localized correction service via MQTT (IP) offers quick delivery of high precision accuracy by providing your device only the SPARTN corrections applicable to your location. This feature offers several advantages over the traditional continental streams, including significantly reduced bandwidth requirements and seamless transition between regions.</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>
