SPP OBSERVATION DATA
This paper introduces an assessment of mobile Internet of Things (IoT) devices embedded with Global Positioning Service (GPS) / Global Navigation Satellite System (GNSS) chip, envisioned to enhance positioning accuracy for safety and on-demand location aware user applications and architecture such as mobile payment applications. This paper extends previous works and proposes a detailed Hybrid assessment, coupling design and performance metrics of Global Navigation Satellite System (GNSS) mobile IoT receivers. The performance evaluation of multi-band mobile GPS/GNSS receivers demonstrated accuracy and precision capabilities for the GNSS observables. Upon those findings, a broad list of performance indicators, metrics and designs parameters are suggested in this paper for future modeling of GNSS tools. The raw GNSS measurements on the RINEX-3.00 format are analyzed using the GNSS-Lab data processing tool (gLAB) and Google GNSS analysis tool. The results show that the multi-band embedded GPS IoT mobile devices outperform single band inbuilt GPS. Moreover, multi-embedded GPS IoT devices offer the best geolocation for on-demand location services in mobile payment applications. The work in this paper can be used to identify the best IoT embedded GPS device recommendation in IoT-based architecture applications such as mobile payment.
Check the GNSS capabilities of your smartphone. Measured parameters including Model name, Android version, Accumulated delta range, Automatic gain control, Navigation messages, HW clock, L5 and GNSS constellations.
Uses the most recent Android API services to log your device's raw GNSS measurement data into a RINEX file including pseudoranges, accumulated delta ranges, doppler frequencies and noise values. So far, it supports GPS/GLONASS/GALILEO/BDS/QZSS for L1/L5/E1B/E1C/E5A (as supported by the device) and has been successfully tested on many devices.
The files are stored in the directory inside the root directory of your internal storage.
To process RINEX data and obtain both GPS standalone or Simple Point Positioning (SPP) solutions : the gLAB tool, Google Gnss analysis tool.
