Beidou卫星数比GPS卫星数多出近1/3, 但定位精度只比GPS定位精度略高一点, 说明GPS定位性能仍非常优越, 在非亚太区域Beidou定位精度不一定会高于GPS. 4. Galileo与GLONASS定位精度远小于GPS与Beidou, 因此在亚太区域Galileo与GLONASS单独的定位结果参考意义有限.

2020年4月24日 · GPS 是 Global Positioning System（全球定位系统）的简称，一般指美国 GPS 系统。国际上投入运行且具备全球定位能力的系统还有俄罗斯的格罗纳斯（GLONASS）和中国的北斗卫星导航定位系统，正在建设中的有欧盟伽利略（GALILEO）定位系统，这些全球卫星定位系统在系统组成和定位原理方面基本一致，可以 ...

2019年4月10日 · Think the GPS companies gives GM and others discount on hardware as long as locked down so they can get some revenue for people to upgrade maps. Be nice if they at least gave you a free map upgrade once a year. But that would conflict with an ongoing revenue stream for a these companies.

2020年1月6日 · ACC-SAT-TO2 from sonicelectronix and of course it had two XM adapters and no pioneer GPS adapter. Amazon was able to send me the correct wires. The connections for XM and GPS use the same connector and was wondering which is which. I think this is GPS: and this is XM because it’s in the same harness as the radio antenna (shark fin). Thanks in ...

2021年2月19日 · So my new truck allows Toyota to read every bit of info from my truck in real time including my GPS location and speed. Now I have already turned off their gracious "complementary" safety connect/service connect but I am almost positive my truck's data can still be accessed by Toyota remotely if they desired.

2013年10月2日 · Not sure about GPS, but all new vehicles sold since 2009 or so have "black boxes" that can be downloaded by insurance companies and probably dealerships in the event of an accident or claim... GPS tracking wouldn't surprise me much, especially in vehicles equipped with a GPS system. Welcome to the post-911 America. Someone is always watching.

又下了gps版的， 幸好官网14天包退，话说回来，蜂窝版真的实用吗？ 我算爱运动的，每周有4天是要户外跑6公里以上的，当初买watch也是看中运动这块，想不戴iPhone跑，试用了几次，不戴iPhone出去跑，发现自己也能接受，户外跑1个小时期间，其实也没有啥人联系 ...

2020年8月28日 · For Entune 2.0, Entune Plus (with Scout GPS), it has a unit under the main head unit that is XM just like you've described. For Entune 3.0, Entune Plus (with Scout GPS), I'm pretty sure XM is integrated and doesn't even need extra box, but I don't have a subscription so I can only verify this with the trial.

2015年11月3日 · Hello, I am the proud new owner of a 2016 Tacoma double cab Limited in Super White.....and new to this forum. My truck will not initialize the GPS. The clock does not work since its getting a feed from the GPS. Also on the Navigation page, the GPS status on the top left of the screen has a red diagonal thru GPS.
