In yaps: Track Estimation using YAPS (Yet Another Positioning Solver)

yaps v1.2.5

New stuff

• Add support for ping_type = 'sbi_doulbe'. Special case - needs carefull contrsuction of TOA-matrix.
• More robustification of the optimizer.
• More pre-flight checks to catch issues with inp.
• Use separate diffusivity for Z when estimating 3D

Bug fixes

• Bug fix - constraint hitting very fast transmitters with BI < 1 relaxed
• Implement better start of top sequence when ping_type = sbi_double

yaps v1.2.4

New stuff

• Now on CRAN
• More checks in checkInp() to catch typical errors in format of inp.
• EXPERIMENTAL Attempt to robustify runYaps() - use with care.

Bug fixes

• Fix bug in getToaYaps() re number of empty pings.
• Docs and examples fixed to meet requirements.
• Make getToaYaps() aware of pingType

yaps v1.2.3

New stuff

• Moved example data hald to an external package with yaps example data yapsdata. Available from github using devtools::install_github('baktoft/yapsdata').
• Lots of examples and tests added.

yaps v1.2.2

New stuff

• New site added to github pages intended to collect yaps-related resources, how-tos etc. (https://baktoft.github.io/yaps/)
• Add first step-by-step tutorial to yaps pages
• Add function to sequentially fine-tune sync model.
• Add option to use speed of sound based on logged temperatur in the synchronisation process.
• Add function to fine-tune sync_model based on residual threshold
• Add plot to check temporal stability of sync_models. Try plotSyncModelResids(sync_model, by='temporal')
• Add option to impose spatial constraints (BBox only) and plot a visual of the constraint. Mainly used to constrain parameter space and increase speed and convergence.
• Add various checks in checkInpSync()
• Add option to use selective downsampling in getInpSync().
• Add function to plot hydros from sync_model - usefull if hydros were re-positioned during getSyncModel().
• Add option to estimate Z-dimension (depth) of tracks.
• Add function to calucate speed of sound from water temperature, salinity and depth - tempToSs(temp, sal, depth).
• Add github actions to hopefully ensure nothing breaks from now on...

Bug fixes

• Fix nasty bug in likelihood contribution of ToP-estimation when using random burst interval (ping_type = 'rbi')
• Fix bug in getInpSync() - failed if sync_tag was only heard on own hydro
• Eliminate estimation of log_sigma_hydros_xy in sync_model
• Relax priors on SS in both track and sync model - consider to switch to softplus instead
• Return plsd object from getSyncModel
• Fix bug in getToaYaps() that allowed too short/too high BI to pass through when using ping_type='rbi' and very fast transmitters
• Fix bug in getToaYaps() that added to many empty pings when ping_type='sbi'.

yaps v1.2.0.9111

New stuff

• Add option to use alternative optimization function (EXPERIMENTAL). Try nloptr() instead of default nlminb(), if you have issues with e.g. false convergence.
• Add option to use linear correction information when running the sync model (EXPERIMENTAL).
• Add option to specify all three ping types in testYaps(). PingType can be 'sbi' (default), 'rbi' or 'pbi'
• Not related to package development, but check out yaps-live https://baktoft.shinyapps.io/yapslive/ to see yaps in action.

Minor new stuff

• Split cpp file into pingType, Edist and ss specifics. Make code more readable and eliminates the need for 'diffuse priors' on parameters.
• Implement testthat functions to ensure future updates doesn't break anything. Work in progress...
• Update readMe.md

Bug fixes

• Fix bug in prepDetections(). Thanks to Hugh Pederson for reporting it.

yaps v1.2.0.9110

New stuff

• Add support for using pressure sensor data as z-values in track estimation
• Add function alignBurstSeq() - aligns detection data with known burst sequence
• Add option to use stationary ref tags as beacons/sync tags without hydro
• Add testYaps() - function to test that everything is running as expected

Minor new stuff

• Add sync_model and known burst sequences to example data hald
• Add extra plots to plotSyncModelCheck()
• Improve diagnostic plots - now violins instead on boxplots
• Add first version of checkInp(). More tests will be added to catch common mistakes
• Added a NEWS.md file to track changes to the package
• Make console output from runYaps() more user friendly - work in progress

Bug fixes

• Fixed bug in getToaYaps() when is.na(eposync) == TRUE
• Add option to ignore extreme values when plotting plotSyncModelCheck()
• Fix issue with sync_model extrapolating eposync beyond period
• Relax initial ss and put gentle constraint on rest ss
• Fix bug in on Attach()
