PointPerfect Flex - locally optimized corrections

Updated

Overview

Introduction

PointPerfect Flex provides locally optimized correction service data via NTRIP, tailored to the user's location with accurate atmospheric corrections. This offers several advantages, including robust performance and significantly reduced bandwidth requirements, while supporting easy integration and seamless transition between regions. 

This page describes our PointPerfect Flex correction service with localized corrections delivered via our NTRIP service.

Benefits of localized corrections data

PointPerfect Flex offers many benefits to users, including:

  • Robust performance and fast convergence time to provide a great user experience.

  • PointPerfect Flex uses the advanced PPP-RTK technology, delivering seamless centimeter-level accuracy in seconds.

  • Low bandwidth requirements: PointPerfect Flex can reduce bandwidth requirements by up to 90% compared to traditional RTK services. This is a significant advantage for applications sensitive to bandwidth constraints, such as those that operate in remote areas or use low-power devices.

  • Uniform coverage: PointPerfect Flex offers consistent coverage across its supported regions. The following article shows the latest coverage areas: the PointPerfect Flex Service Coverage article.

  • High reliability and availability: PointPerfect Flex is backed by u-blox's global network of reference stations, ensuring high reliability and availability even in challenging environments.

Do's & Don'ts: Best Practices and Common Pitfalls 

Do's: 

  • Check out our Python sample script PointPerfect Flex NTRIP Client: Our sample script located within the Thingstream Downloads page for PointPerfect Flex can give you a great example on how to implement this into your setup.  

  • Keep your F9 or X20 receiver firmware up to date: Regularly update your receiver firmware to ensure compatibility with SPARTN corrections and to benefit from performance enhancements, bug fixes, and new features. 

  • Send GGA messages every 10 seconds: The NTRIP server needs a current GGA message from the rover to ensure correct localized corrections. Most NTRIP Clients are set to send GGA every 10 seconds. (The NTRIP server disconnects if no GGA is sent within 60 seconds.)  

Don'ts: 

  • Don’t send inaccurate GGA messages: Some NTRIP Clients send fixed or “baked” GGA messages that don’t reflect the rover’s real-time position. This can lead to DGNSS or Float problems. Always ensure GGA messages reflect the rover’s current location. 

  • Don’t use  the same login credentials on multiple devices at once. Doing so will lead to frequent disconnect and reconnect issues.
