Information Modes
The HiPer+ has two information modes: Normal and
Extended Information Mode (EIM).
Normal
In normal mode, the STAT LED indicates the number of
tracked satellites and the position’s computation status.
Extended Information Mode (EIM)
Extended Information Mode is used for receiver testing
purposes. In this mode, the receiver continues to work as
usual, but the STAT LED indicates the following
“extended” information:
• Delimiter – an easily distinguishable double-blink
that shows the overall status of tests performed in
EIM. The STAT LED color for delimiter is calculated
from the colors of other STAT LED blinks.
–Orange: at least one blink is orange.
–Red: no orange blink and at least one red blink.
–Green: all other cases.
• Sufficient data for position computation.
• GPS S/N ratio is good (see Table 4-2).
• GLONASS S/N ratio is good (see Table 4-2).
• Oscillator’s frequency offset is less than three ppm.
• Oscillator's Allan Variance is better than 2.7e-10.
• Continuous tracking time is more than 15 minutes.
