#225 | fixed | Specim synchronisation error | mggr | mggr |
Description |
Descriptive email from Ben to Bill (4/Mar/2009): We were (still) trying to track down our Vocals offset problem and we think we stumbled across something else. We used CaliGeo to process a line that had had a timing error in it when we'd processed it using the az suite, and CaliGeo didn't produce a timing problem. We noticed that in the bit where Caligeo is looking for sync the message it finds has a time delay of 548ms, which matches the 548 in the "Navsync Timing" line on the line 5 header file. The previous sync message it found (and discarded) had a time delay of 119ms, which matches the Navsync Timing for line 4. Azimport for that line found a specim sync message offset of 0.119, which suggests to me that it actually picked up the sync message for line 4 rather than 5. Can you take a look at this when you get a chance please? Let me know if I can send you any additional test data. |

#73 | fixed | Specim sync errors | mggr | mggr |
Description |
Many 2007 flight lines have problems with navigation sync (ie. they don't sync!). This appears to be due to missing sync messages in the .nav file, or a totally missing .nav file. A typical error looks like: -------------------------------------------------------------------------- azimport -- ver: 2.2.10 May 7 2007 (C) Azimuth Systems UK 1996, 2007 File template for Specim sync is: hawk/SWIRsh2007130#.nav Site time limits - day: 130 start: 94341 end: 94609 date: 10 05 2007 jday: 130 utc2gps: 14.0 NAV vgroup exists - updating Specim navigation sync details from image file header..... image lines: 2901 approximate sync time: 35021.46880 (gps SoD) frame inc: 0.05000 secs sensor: Hawk frame rate: 20.00 fps no. of frames to correct for: 3.00 sync time: 35021.5 is NOT on Applanix POSATT file: hawk/SWIRsh2007130a-1.nav start: 35182.8 end: 35403.5 sync time: 35021.5 is NOT on Applanix POSATT file: hawk/SWIRsh2007130a-2.nav start: 35421.1 end: 35565.1 sync time: 35021.5 is NOT on Applanix POSATT file: hawk/SWIRsh2007130a-3.nav start: 35752.3 end: 35869.1 sync time: 35021.5 is NOT on Applanix POSATT file: hawk/SWIRsh2007130a-4.nav start: 36085.1 end: 36243.4 ** NO Specim SYNC found after checking all files ** check file template and directory contents - no data saved A procedure to correct for this is outlined in the specim processing guide but appears only to apply to azspec 1.1.3. We have azspec 1.1.2. |

#198 | fixed | Southern hemisphere processing not working | benj | benj |
Description |
Using the -mTMS flag in azgcorr to denote southern-hemisphere processing causes either a segfault or north-south inverted results. Have had a couple of potential fixes exchanged with Bill (not quite right yet though), raising this mostly to go with the work order. |
