Parameters
- db
- Type: GeoEngine.Core.GXNetCDB
DB Object - line
- Type: SystemInt32
Line to process (NULLSYMB for all selected lines) - raw_radar_altimeter
- Type: SystemString
Input (BP-filtered) radar altimeter channel name - pressure_channel
- Type: SystemString
Input pressure channel name (kPa) - temperature_channel
- Type: SystemString
Input temperature channel name (degrees Celsius) - stp_alt_channel
- Type: SystemString
Output STP corrected altimeter channel name
Remarks
The output STP corrected altitude is calculated using the formula:
STP_Altitude = (273.15 * radar_alt * P))/((273.15 + temp) * 101.325)
where:
STP_Altitude = STP corrected altitude (m)
radar_alt = raw radar altimeter channel value (m)
P = raw pressure channel value (kPa)
temp = temperature channel value (degrees Celsius)
