| | applying the realtime-derived receiver | |
| | clock offset: 1=yes, 0=no; default: 0=no | |
| | Record required if clock offsets are | |
| | reported in the EPOCH/SAT records | |
+--------------------+------------------------------------------+------------+
*|LEAP SECONDS | Number of leap seconds since 6-Jan-1980 | I6 |*

| | same time frame as observation time tags)| |
| | - "Number of satellites" contains number of | [I3] |
| | special records to follow. | |

| | | |
| | If epoch flag = 6: | |
| | 6: cycle slip records follow to optionally | |
| | report detected and repaired cycle slips | |
| | (same format as OBSERVATIONS records; | |
| | slip instead of observation; LLI and | |
| | signal strength blank or zero) | |
+-------------+-------------------------------------------------+------------+
|OBSERVATIONS | - Observation | rep. within record for | m(F14.3, |
| | - LLI | each obs.type (same seq | I1, |
| | - Signal strength | as given in header) | I1) |
| | | |
| | If more than 5 observation types (=80 char): | |
| | continue observations in next record. | |
| | | |
| | This record is (these records are) repeated for | |
| | each satellite given in EPOCH/SAT - record. | |
| | | |
| | Observations: | |
| | Phase : Units in whole cycles of carrier | |
| | Code : Units in meters | |
| | Missing observations are written as 0.0 | |
| | or blanks. | |
| | | |
| | Phase values overflowing the fixed format F14.3 | |
| | have to be clipped into the valid interval (e.g.| |
| | add or subtract 10**9), set LLI indicator. | |
| | | |
| | Loss of lock indicator (LLI). Range: 0-7 | |
| | 0 or blank: OK or not known | |
| | Bit 0 set : Lost lock between previous and | |
| | current observation: cycle slip | |
| | possible | |
| | Bit 1 set : Opposite wavelength factor to the | |
| | one defined for the satellite by a | |
| | previous WAVELENGTH FACT L1/2 line.| |
| | Valid for the current epoch only. | |
| | Bit 2 set : Observation under Antispoofing | |
| | (may suffer from increased noise) | |
| | | |
| | Bits 0 and 1 for phase only. | |
