可以通过订阅DJI::OSDK::Telemetry::RTK::posHealthFlag查看,该Flag的可能值如下
0 - no solution
1 - Position has been fixed by the FIX POSITION command
2 - Position has been fixed by the FIX HEIGHT/AUTO command
8 - Velocity computed using instantaneous Doppler
16 - Single point position
17 - Pseudorange differential solution
18 - Solution calculated using corrections from an SBAS
19 - Propagated by a Kalman filter without new observations
20 - OmniSTAR VBS position (L1 sub-metre)
32 - Floating L1 ambiguity solution
33 - Floating ionospheric-free ambiguity solution
34 - Floating narrow-lane ambiguity solution
48 - Integer L1 ambiguity solution
49 - Integer wide-lane ambiguity solution
50 - Integer narrow-lane ambiguity solution
当flag为0时,RTK无解并且不会输出经纬度;当flag为1-49时,RTK会更新经纬度信息,但准确度不高;只有当flag为50时RTK才是fix状态.
