4.9.1.1 Precision 

Menu 

The 

Precision@

 menu provides information relating to the estimated real-time 

precision of position computations.  Please note that these are not absolute accuracy 
estimates, but only relative measures.  This menu is detailed in Figure 4-9. 

Res rms:  0.3m?A   
=_a:??????0.2m?^ 
=_b:??????0.1m 
Azimuth:163.1! 
=_Lat:????0.2m? 
=_Lon:????0.2m 
=_Alt:????0.3m 
Back@ 
Top Menu@ 

 

Pressing the 

 and 

 keys allows you to scroll through the available menu items.  

Pressing the 

 button anywhere in this menu will provide a bar chart of signal 

tracking information.  Pressing the 

 button with the 

Back@

 or 

Top Menu@

 item 

in focus will take the menu system to the previous menu or the Main menu, 
respectively.   

Res rms:  0.3m 

A

 

 

This menu item displays the root mean square of 
the residuals that result from a position 
computation.  This value provides an estimate of 
the position accuracy, and approximates one 
standard deviation of horizontal precision. 

 

 

=_a:      0.2m?^ 

 

This menu item indicates the length of the semi-
major axis of the horizontal position’s error 
ellipse, to a confidence of one standard deviation. 

 

 

=_b:      0.1m 

 

This menu item indicates the length of the semi-
minor axis of the horizontal position’s error 
ellipse, to a confidence of one standard deviation.
