@Luís-Pinto dual frequency atm doesn’t offer anything. I have the one plus that supports it and meh.just commenting on this

[Luís Pinto]

@Dimitrios-Kanellopoulos (OnePlus) Did you try in static mode or moving or both?

[Dimitrios Kanellopoulos]

@Luís-Pinto all modes. I wanted to use it as reference but was always worse than my s9

[Luís Pinto]

@Dimitrios-Kanellopoulos Serious? Every technical report says the opposite… https://www.esa.int/Applications/Navigation/Dual-frequency_smartphone_app_winners_prove_power_of_two

[Dimitrios Kanellopoulos]

@Luís-Pinto we have talked about it again at your post. You missed I suppose the Ghostbusters antenna setup.

[Dimitrios Kanellopoulos]

Yeah right or am I wrong ?

Feel free to ask for tracks. Actually let me post my accuracy

[Luís Pinto]

@Dimitrios-Kanellopoulos Yes i remember. Yes, antenna that these guys used is like total stations (ex: Leica systems).

[Dimitrios Kanellopoulos]

@Luís-Pinto

I see l5 and e5 but no accuracy increase

@Dimitrios-Kanellopoulos maybe in small devices with internal antennas like smartphones the usefull is marginal. Curious normally every sat have different frequencies, but in your printscreen i see just one Navstar (L1 and L5), two in Gal(E1 and E5) and no one from Glonass and Beidou. BDS-3 sats have this capability and glonass K.

[Luís Pinto]

@Dimitrios-Kanellopoulos Beidou signal in your printscreen is cool: two sats with > 30.

[Luís Pinto]

@Dimitrios-Kanellopoulos I read from you that you are getting good results with Nav+BDS solution. Did you confirm?

[Dimitrios Kanellopoulos]

@Luís-Pinto yes sir. The best in line. I ditched gali

[Dimitrios Kanellopoulos]

@Luís-Pinto gali can be more accurate , eg more close lines on come and go under good conditions. Beidou did never fail me

[Luís Pinto]

@Dimitrios-Kanellopoulos In all different activities? Hiking/running/bike?

Terrestrial corrections are very important for system integrity. It’s what makes diference in american system WAAS for so long. Europe is getting stability with EGNOS (but need more redundancy), and China with SNAS.

@Chan-Wai-Kit Always on screen will eat into your battery life. If you can use powersave tilt. I did a 4h 40 min run today and finished with 32% battery left.

[Luís Pinto]

Every have relation with time, sats have atomic clocks with nanoseconds of precision. But there are small delays in transmission for earth=time travel (ionospheric perturb…). Ground stations make that corrections. Time is crucial for accuracy, i.e time/space, time cannot be separated from the three dimensions of space. One coin, two faces, same to determine continuum (Einstein stuff).

[Dimitrios Kanellopoulos]

@Luís-Pinto yeah.

I use my app typically to see what could perform best. In France and Greece beidou has the most sats, and best signal

Beidou is big
