CourseSpeed

Version 9.1.1: 1. Added the fields: -- Cache Lat Distance, -- Cache Lon distance, and -- Cache Avg Count to the CourseSpeedWatch app whenever the "Use Mark as Geocache" switch is set to 'on' in the CourseSpeed iPhone App's 'Settings' view.". These fields are calculated by the CourseSpeed iPhone App. 2. Changed the number of GPSr reports used for averaging a geocache location from 50 to 10 in the CourseSpeed iPhone App.

Fixes an issue when using the Mark as a geocache. The values for the distance to the latitude line and distance to the longitude line of the geocache were incorrect.

1. A new feature has been added for Geocaching. The new feature allows for finding the given cache location by providing two independent distances to the geocache, one in the north-south direction and one in the east-west direction. This makes it easier to zero in on the cache. In addition, only the GPSr positions marked with the best accuracy (by the GPSr) are used in the averaging of the user’s current location. (Note: Geocaching is a “treasure hunt” using a GPS receiver, like the one in your iPhone! See the geocaching.com web site for details about geocaching). 2. In the Map View, the Magenta track line distance has been fixed to be displayed in the distance units selected by the user in the Main View. Previously, it had been displayed only in miles. The red track distance did not need to be fixed as it was already displayed in the proper distance units. 3. In the Settings view, the choices for the type of course smoothing have been simplified to only one type.

Version 8.18(0) - Fix for occasional App crash seen in V8.16(5).

Version 8.17(8) - Removed the settings switch for displaying speeds near zero (i.e., less than 1). Now, the lowest displayed speed will be 1. - Added a settings switch to allow the user to select speeds less then 10 to be displayed with or without a fraction.

Version 8.16(5) - Fixed a startup issue in V8.15(11) where speed was not set to zero in a timely fashion in the case of a stationary user but the first GPS location indicated a non-zero speed. Also contains recent Version 8.15 changes. Click on the Version History link to see those changes also.

Version 8.15(11) - Added an Anchor-Watch function, for boaters, that sounds an alert tone when a boat at anchor is found to move by an unacceptable distance, selectable by the user. The selectable distance is saved to a file in order to have the same setting when restarting the App. - Changed Speed-Made-Good-to-Mark functionality to Speed-Made-Good-to-Windward. Added operator entry for wind direcction and as a switch in the Settings view to enable the Speed-Made-Good-to-Windward function. Saved the value of wind direction and the enable/disable status of the new switch to a file in order to have the same settings when restarting the App. You can still add a Mark on the map and still see the distance and bearing to the Mark in the same fields on the Map view. - Fixed an issue in the Map View where a track history could not be stopped if a waypoint was added to the current track history track and there was not a GPX track recording started. - Better rejection of obviously bad GPS receiver locations. - In certain instances, when it is questionable whether the GPS receiver's speed or course is correct, we are computing speed and course from the last two GPS receiver latitude/longitude pairs instead of using the GPS receiver values for speed and course. - When course is changing quickly, e.g. turning sharply, display the new course immediately instead of passing it through the course smoothing algorithm. - Other, non visible improvements.

Version 8.14(2)  Removed a change made in Version 8.13(3) that inadvertently caused the Map view to be updated at a slower than normal rate.

April 19, 2021

Version 8.13(3) - Corrected the algorithm for computing "Julian Day" to include the current time zone offset from UTC time. Julian Day is used in all astronomical calculations, including in the CourseSpeed App's Apple Watch "Sun Rise/Set" complication showing sunrise and sunset times of day. - Other, non visible improvements.

V8.12(2) - Added an Apple watch "complication" to show the times of Sunrise and Sunset at your current location. The times are calculated and updated periodically as the Sunrise and Sunset times will change based on your current position. The calculations for the times of sun rise/set take into account the light refraction at the horizon as well as the radius of the sun. Both are needed in order to accurately represent the time at which the observer actually sees as the sun rise/set. The following complication families are supported: Modular Small,  Modular Large,  Utilitarian Large, Utilitarian Small Flat,  Extra Large,  Graphic Corner, Graphic Bezel, Graphic Rectangle, and Graphic Extra Large. Add the Sun Rise/Set complication to your watch as you would any other Apple Watch complication. - Other, non visible improvements.
