Sun Compass & Sunrise/Sunset V3.3 (only for Palm-Pilot with OS Version 2.0) If you've Palm-Pilot OS1.0, please use the older Version 2.4! (It's to download from my Homepage) What is new in Version 3.3 ? ----------------------------------------------------------------------------- Have changed to normal Sunrise and Sunset Times. That means if sun is a half degree under the horizont! I made this on request of some other people! ----------------------------------------------------------------------------- What was new in Version 3.2 ? ----------------------------------------------------------------------------- If you tap on the date-area or time-area at the bottom of the screen, you can change the date and the time. Each restart of sun-compass will reset the time to the current time, or you simply select it again and tap on the OK-Button (without any select) ! ----------------------------------------------------------------------------- What was new in Version 3.1 ? ----------------------------------------------------------------------------- If you tap on the date-area at the bottom of the screen, you can change the date. Now, you can see all values (sunrise/set & sunangles) specific for this new choosen date! Each restart of sun-compass will reset the date to the current date! ----------------------------------------------------------------------------- What was new in Version 3.0 ? ----------------------------------------------------------------------------- This Version is now working 100% accurate. Why? Now,I've used a complex and voluminous formula. This formula calculates the following variables: 1. Declination 2. Equation of Sun 3. Local Solar Time 4. Hour Angle 5. Altitude Angle 6. Azimuth Angle <--- I use this angle to calculate the NORTH-direction exact! 7. Time of Sunrise 8. Time of Sunset These variables you can see, if you tap on the Sun-Info-Graphic-Button! I have to calculate with functions like (sin,asin,cos,acos...), so this prog needs the MATHLIB.PRC file! Don't forget to load it before you start Sun-Comp Before you begin, you have to input the following values: Longitude (Lo-Field), Latitude (La-Field), Timezone (Tz-Field), Daylight-Saving Time (Graphic-Button). That's all. Please, also read the instruction within the sun-compass programm via the pulldown-menu !!!!!!!!!!!!!!!! ----------------------------------------------------------------------------- Were is the NORTH ??? ----------------------------------------------------------------------------- With this program you can simply determine the NORTH-DIRECTION. You only need your Pilot and the sun! ----------------------------------------------------------------------------- Polar-Star: ----------------------------------------------------------------------------- Get the Pulldown-Menu and choose Polar-Star. Here you'll see, how to get NORTH, by searching the "great dipper". With the "great dipper" you can find the Polar-Star. Note: Have you got the Polar-Star, then you've got NORTH! The Polarstar you'll only see on the northern hemisphere! ----------------------------------------------------------------------------- How to practice? ----------------------------------------------------------------------------- Turn your Pilot in direction to the sun, but hold your Pilot horizontal. Now, you can read the North-Direction on the screen ! The Pilot is calculating the North-Direction every minute automaticly. ----------------------------------------------------------------------------- Registration: ----------------------------------------------------------------------------- If you like to register: Please send $5 US (no cheque) to: Thomas Jawer Gabainstr.12a 12247 Berlin Germany That's it.
