Phase Differential (RTK) Parameters
Number of Epochs to Use for Self-calibration
Name:
Access:
Type:
Values:
Default:
/par/att/naver
rw
integer
[1…2000000]
60
The number of measurement epochs must be set taking into consideration the following:
1. Minimum self-calibration time is 1 hour;
2. Recommended self-calibration time is greater than 1 hour;
3. Maximum self-calibration time is 2 hours.
According to the above, the number of measurement epochs can be determined as:
N = Tcalibration / Tinterval
where
Tcalibration – self-calibration time,
Tinterval – differential corrections update period.
For example, if differential correction update period is 0.05 s (1/20 Hz) and Tcalibration
is 1 hour, then
N = 3600 / 0.05 = 72000
Start Self-calibration
Name:
/par/att/tune
Access: rw
Type:
boolean
Values: on,off
Default: off
on – the self-calibration process will begin. The value of this parameter is immediately restored to off.
off – ignored.
Base Line Vectors of the Body Frame
Name:
/par/att/bl/N (N=[0,1,2])
Access: rw
Type:
{n,r,b}
Default: {0,0,0}
n, r, b – Nose-, Right-, Belly- components of the corresponding vector. Float values in the range [-100000…100000] meters.
