I have measured phase difference and get wrong data.
Help me please to find solution.
A1 - antenna 1
A2 - antenna 2
S - satellite
Sat pos 1 - satellite position in T1
Sat pos 2 - satellite position in T2
В - A1-A2 lenght (5m)
Cos(α1)= λ*(Ф2-Ф1)/(2*π*B)=λ*(φ12-φ11+k)/(2*π*B)
φ11, φ12 - pseudophase, read from receiver
k - number of ambiguity cycles
Cos(α2)=λ*(φ22-φ21+k)/(2*π*B)
Cos(α2)-Cos(α1)=λ*((φ22-φ21)-(φ12-φ11))/(2*π*B)
Cos(α2)-Cos(α1)=λ*Δφ/(2*π*B)
Δφ=2*π*B*(Cos(α2)-Cos(α1))/λ
A1 coordinates in WGS84:
x=2352338.526
y=2718871.727
z=5250711.535
A2:
x=2352337.383
y=2718876.244
z=5250709.721
T1=133200 (13h 32m 00s UTC)
T2=133201
SatPos1:
xj1=-16213258.59
yj1=7225892.91
zj1=19698260.91
SatPos2:
xj2=-16215421.53
yj2=7224579.41
zj2=19696990.78
Cos(α1)=0.12834301654361024
Cos(α2)=0.1283298031315633
Phase difference calculated from coordinates:
Δφ=2*π*B*(Cos(α2)-Cos(α1))/λ=-0.002181426087639554
Phase Difference Received from Receiver (PSTMTS message):
Δφ=(φ22-φ21)-(φ12-φ11)=(-51388.13+51106.71)-(-51387.36+51106.91)=-0.97
