They are NEWEST, BEST, MOST ACCURATE, MOST CAPABLE system globally STRONGEST.
Strongest meaning the strongest fleet of satellites in numbers in the orbit.
Most Capable because they are the ONLY 2-WAY capable system. All the rest are just 1-way system. 2-way meaning you can send & receive SMS via BDS-3 satellites from anywhere on earth as long as you can see sky. If you were in underground carpark cannot, must be @ open sky or at least near window. It is not your regular telco's SMS, but BDS-3 SMS, you got to have their A/C and App installed. Chinese ships and fishing boats all have this. During their beginning stage of BDS-1 they were offered FOC to fishermen. Now may be a tiny token fee or could be still FOC, I don't know.
BDS is MUST HAVE, and many countries are cancelling their GPS and switched to BDS-3, because USA is unreliable and greedy bastard. They fuck with GPS system to sabotage especially during conflict and wars. Now using BDS-3 & Glonass (Putin's) which both already combined as 1 single system, they DEPRIVED Dotard Pentagon to screw with GPS hoping to win by that - if they did, they only screw their own sucker followers like you! The 1B1R friends are OK, and systems all working and will win wars with that.
Key Legend for the Satellite Types, the + sign are BDS = Beidou the round dot are Dotard's GPS, the Triangles are Putin's Glonass.
The pentagon shapes are European Galilio, Squares are Japs QZSS = Japs is the poorest system with just only 4 satellites.
There is another which is the BIG TALK ABNN Ah Neh talkcock system which has nothing but empty talks.
