## Project Stages

- The mathematics:
- Calculating modified Julian Day number (JD)
- Calculating Greenwich Mean Sidereal Time (GMST)
- Calculating Universal Time
- Calculating the Right Ascension (RA) and Declination (Dec) of the Sun.
- Calculating sun rise and sun set or any other position of the sun.
- Calculating your Longitude based on sun rise and sun set times.
- Calculating your Latitude based on sun rise and sun set times.
- Some code to try.

- A box to put the electronic in.
- What could be so hard with samping daylight:
- The need for an accurate Real Time Clock
- The rotary encoder as an input device
- Code to read the rotary encoder
- A menu system
- Setting the time
- Saving your data
- Remembering settings
- Downloading your data
- Dealing with power outages (restarting as if nothing happened)

- Processing your data:
- Using a "solver" to fit a model to the collected data
- The solver
- Creating a model
- Getting an initial estimate
- Dealing with cloud and sensor locational issues

Checked FM RDS and only clock signals are in Tasmania (~3000km).

Its only 8000km to Toyko which has 40kHz and 60kHz signals.

May be able to pick these up from time to time for updates (another project!).
