This application enables you to see where the Quasi-Zenith Satellite System in the sky! ●What is QZSS? Quasi-Zenith Satellite System (QZSS) is a Japanese satellite positioning system composed mainly of satellites in quasi-zenith orbits (QZO). Satellite positioning systems use satellite signals to calculate position information. One famous example is the American Global Positioning System (GPS) and the QZSS is sometimes called the Japanese GPS. For details, please refer to the following Website "Quasi-Zenith Satellite System". URL : https://qzss.go.jp/en ●What is GNSS View? GNSS View provides that iOS version application that is based on the website application "GNSS View". This application enables you to know position of positioning satellites such as QZSS and GPS in the specified time and location. The positioning satellites displayed in the GNSS View are not based on the satellite information directly received by the smartphone but are displayed based on the satellite arrangement calculated based on the publicly released orbit information. ●GNSS View 3 functions 【Main】 ・You can move to the Position Radar screen or AR Display screen from the application startup screen. ・You can see the operating manual and privacy policy of this application via the website. 【Position Radar】 ・It is provided radar view of positioning satellites such as QZSS and GPS as a sky plot at the specified time and location. ・Positioning satellites can be specified from QZSS, GPS, GLONASS, BeiDou, Galileo, SBAS. ・You can also select specified signal satellites to see on the radar. ・You can see selected satellites by setting elevation mask angle. ・You can switch east and west of satellite arrangement, turn on / off rotation, and switch on / off display of satellite number. ・It displays HDOP, VDOP, the total number of satellites and the number of each positioning satellites in the satellite arrangement displayed on the radar. 【AR Display】 ・Position of positioning satellites such as QZSS and GPS on the sky from your current location is able to see through your camera at the specified time. ・In order to display satellites, it is necessary to turn on the position information of the smartphone and complete the positioning. Therefore, it may take time to display. ・Positioning satellites can be specified from QZSS, GPS, GLONASS, BeiDou, Galileo, SBAS. ・You can also select specified signal satellites to see on the radar. ・You can see selected satellites by setting elevation mask angle. ●Supported versions ・iOS 26 ・iOS 18 ・iOS 17 ・iOS 16 ・iOS 15 ・iOS 14

Eos Tools Pro is a monitoring utility for the Arrow and Skadi series high precision GNSS receivers from Eos Positioning Systems. It provides advanced GNSS information such as RMS values, PDOP, differential status, satellites tracked and used, that are critical for submeter and centimeter GIS and surveying data collection. The app features a built-in end trip client to access RTK or DGNSS corrections from an RTK network. Eos Tools Pro also allows audible user configurable alarms and runs in the background of your mapping surveying software. Features: - Built-in NTRIP client to connect to an RTK Network - Displays GNSS and Tilt Compensation accuracy with quality control information - Select the Skadi Smart Handle mode: Extensible Virtual Range Pole™ or Invisible Range Pole™ - Satellite view for all constellations in use (GPS, GLONASS, BeiDou, QZSS and IRNSS) - User configurable alarms - Orthometric Height (Geoid models for vertical datum) - Compute and apply Position Shifts to accommodate different - Laser Offset Mapping for Esri ArcGIS® Field Maps - Locate and map underground utility assets directly in ArcGIS Field Maps - Terminal emulator to send configuration commands to the receiver - HTML5 built-in browser Disclaimer: "Continued use of Eos Tools Pro running in the background and connected to the GPS/GNSS receiver can dramatically decrease the battery life of your Apple device."

Verdict
The clearest difference is review sentiment: GNSS View at 69% against Eos Tools Pro's 38%. GNSS View also leads on iOS requirement (14.0 vs 17.0). Eos Tools Pro's advantage is rating (4.6 vs 4.3) and update cadence (every 2 months vs every 7 months). On price, ratings volume, ads and in-app purchases there is nothing between them.
