The results indicate that the system time differences of GPS with BeiDou, GLONASS and Galileo are very stable over time with STD values of better than 1.1 ns. View Show abstract • GPS+Galileo is better than the combined GRE solution, when estimating periodic terms (reduction of the 1/3 harmonic). From the analysis of the orbit quality we know, however, that periodic terms ECOM1 (E1) should be estimated. Thus, E0 is not the best solution for other GNSS-based parameters.

Directions 2023: Galileo Offers New Services. In 2022, the Galileo GNSS continued to provide the world’s most precise satellite navigation information, to a user base that stands at more than 3.5 billion worldwide. Furthermore, provided services continue to improve and expand, with plans for high-accuracy positioning and signal authentication
Galileo HAS is a revolutionary new high-accuracy Precise Point Positioning (PPP) correction service available around the globe, with enhanced performance in Europe. Galileo HAS is a dual-constellation, multi-frequency correction service, with support for the following Galileo and GPS signals: Galileo: E1, E5A, E5B, E6B. GPS: L1, L2C, L5. New and improved satellites. The Global Positioning System (GPS), one of the world’s first such satellite systems, has changed the way billions of people move around. Since 1993, at least 24 GPS The red one is the Galileo track and it’s probably the better of the 3 over this entire section but not so great on the top right. Here are the same 3 Garmin tracks on the other part of the track. With just tree cover as the issue, they look pretty similar to me at the start of the route. Pink 935 Glonass, Red 935 Galileo, Yellow 935 GPS.
Since the GPS L5 signal has an expected power 1.5 dB above the L1 C/A signal power, the sensitivities considered for the L5 signal are −138.5 dBm, −143.5 dBm, −148.5 dBm, −153.5 dBm, and −158.5 dBm. This allows us to do a fair comparison representative of the reality. The same will apply for the Galileo signals.
The official status of the project (‘initial services’) says that availability will be “better than 77%”, which belies the ‘better than GPS’ claims. GPS and Galileo are engineered to be used in combination, and this combination is indeed superb. The EU GNSS Agency (GSA) which is in charge of operating Galileo relies heavily on industry.

Using a combination of GPS and Galileo is great for getting around unknown cities, especially in Europe. Positional Accuracy. Since 2023, Galileo has had the highest accuracy of all three GNSS with a horizontal accuracy of 20cm and a vertical accuracy of 40cm. That is impressive if you compare Galileo to GPS or GLONASS.

Galileo is Europe’s own global navigation satellite system, providing a highly accurate, guaranteed global positioning service under civilian control. It is inter-operable with GPS and GLONASS. Galileo receivers compute their position in the Galileo Reference System using satellite technology and based on triangulation principles . The
In general, the positioning performance of BDS-3 was slightly better than those of GPS and Galileo in the Asia-Pacific region, and it is believed that with the continuous development of BDS, its

The new models (eg. 955) have a “All systems” option instead of GPS+Glonass, GPS+Beidou, etc, and cycle between 2 systems depending on the actual conditions during the run. So one moment you might be using GPS+Glonass, then 30 minutes later GPS+Galileo, then Beidou, etc (some people can run REALLY far in one session). 🙂

The combined use of multi-GNSS systems in positioning, navigation and timing requires taking into account the variable time offset between the individual system times. This offset can be determined at the user level as an additional unknown in the position-velocity-time (PVT) solution when a sufficient number of satellites is visible. However, a known value of the inter-system bias can also be
All valid points. Key thing in a car is power and board-space are “relatively” unlimited. A GPS puck in a car is typically a 1-2″ lump (containing inside it the antenna)… if you compare that to your watch, the GPS antenna module alone for a car GPS would be larger than the entire watch (leaving no room for watchy-things).
