 To provide users with a quick snapshot of the status of the TimeHat system, I created a simple web page that shows things like the system uptime, temperature from the CPU and RTC, chrony status, gpsd status, and current satellite map and historical satellite heat map.  To provide users with a quick snapshot of the status of the TimeHat system, I created a simple web page that shows things like the system uptime, temperature from the CPU and RTC, chrony status, gpsd status, and current satellite map and historical satellite heat map.

 +This script generates two JSON files which are placed in ''/var/www/html/'' - ''timehatstats.json'' and ''satplot.json''. The first is where the general system information is stored, and the second is where the heatmap log is stored. Check out the examples below. The main configurable parameter of the info getter python script is whether or not to obfuscate the location. Some users may choose to expose this on the public web, but not want to share their precise location. The obfuscation routine simply truncates the latitude and longitude to two decimal places. E.g. - 44.1234567 gets trimmed to 44.12.
