The information (CON) is derived by the SDPS, is implementation dependent and shall be described in the ICD. 2. The information (PSR), (SSR), (MDS), (ADS) and (MLT) and well as (OPS), (ODP), (OXT), (MSC), (TSV), (SPO) and (TTF) are derived from the monosensor service message categories and are only relevant for operational sensors (i.e. CON = 0). 3. The sensor status derived from the SDPS indicating the use of a specific technology is provided in I063/REF/SSFS/PSR, I063/REF/SSFS/SSR, I063/REF/SSFS/MDS, I063/REF/SSFS/ADS and I063/REF/SSFS/MLT. 4. This legacy I063/060/NPW “No Plot Warning” might be either sensor or SDPS derived. A SDPS derived “No Plot Warning” is available in I063/REF/SSS/NPWS. 070 "Time Stamping Bias" definition Plot Time stamping bias, in two’s complement form element 16 signed quantity 1 "ms" 080 "SSR / Mode S Range Gain and Bias" definition SSR / Mode S Range Gain and Range Bias, in two’s complement form. group SRG "Mode S Range Gain" element 16 signed quantity 1/100000 "" SRB "Mode S Range Bias" element 16 signed quantity 1/2^7 "NM" remark Note: The following formula is used to correct range: .. math:: \rho_\mathrm{corrected} = \frac{\rho_\mathrm{measured} - range\_bias}{1 + range\_gain} 081 "SSR Mode S Azimuth Bias" definition SSR / Mode S Azimuth Bias, in two’s complement form. element 16 signed quantity 360/2^16 "°" remark Note: The following formula is used to correct azimuth: .. math:: \theta_\mathrm{corrected} = \theta_\mathrm{measured} - azimuth\_bias 090 "PSR Range Gain and Bias" definition PSR Range Gain and PSR Range Bias, in two’s complement form. group PRG "PSR Range Gain" element 16 signed quantity 1/100000 "" PRB "PSR Range Bias" element 16 signed quantity 1/2^7 "NM" remark Note: The following formula is used to correct range: .. math: \rho_\mathrm{corrected} = \frac{\rho_\mathrm{measured} - range\_bias}{1 + range\_gain} 091 "PSR Azimuth Bias" definition PSR Azimuth Bias, in two’s complement form. element 16 signed quantity 360/2^16 "°" remark Note: The following formula is used to correct azimuth: .. math:: \theta_\mathrm{corrected} = \theta_\mathrm{measured} - azimuth\_bias 092 "PSR Elevation Bias" definition PSR Elevation Bias, in two’s complement form. element 16 signed quantity 360/2^16 "°" RE "Reserved Expansion Field" definition Expansion explicit re SP "Special Purpose Field" definition Special Purpose Field explicit sp uap 010 015 030 050 060 070 080 081 090 091 092 - RE SP
