The following data fields appear on the Location/GPS tab of the settings page, in the popup 
that appears when you hover over the GPS icon in the new interface, and near the top of 
the GPS Bar in the classic interface:

●

GPS Port — The next available NMEA Port available for use by a GPS Application. 
Some applications require you to enter this port number.

●

Heading — The approximate direction in which you are moving. Compass headings 
range from 0 degrees (due North) to 360, with 90 being due East, 180 being due 
South, etc.

●

Speed — The estimated speed at which you are moving.

●

Latitude — Your current latitude, expressed in degrees and rounded to four decimal 
places. Positive numbers are used for locations north of the equator. Negative 
numbers are used for locations south of the equator. Zero is the equator itself.

●

Longitude — Your current longitude, expressed in degrees and rounded to four 
decimal places. Positive numbers indicate locations east of the Prime Meridian 
(which passes through Greenwich, England). Negative numbers indicate locations 
west of the Prime Meridian.

●

HEPE — Horizontal Estimated Position Error. This is a measure of the accuracy of your 
calculated position. So, if the HEPE is 43 feet, you could be as much as 43 feet from 
the coordinates indicates by your device’s GPS receiver.

●

Satellites — The number of satellites your GPS receiver has acquired. At least three 
are required to provide latitude and longitude and four are required to provide an 
altitude. Additional satellites provide greater accuracy (seven or more is considered 
excellent).

●

Last Fix — The date and time that your device’s GPS receiver was last able to update 
its location data.

●

Altitude — Your current altitude above Sea Level (in feet). Note that because of the 
inherent difficultly in determining altitude via GPS, the margin of error for altitude may 
be somewhat larger than the HEPE (the margin of error for latitude and longitude).
