Appendix C Frequently Asked Questions
Communication
Question: Do I need a 10 Hz output?
Answer:
No. The Axis
3
receiver’s output rate is 5 Hz, which is
suitable for most applications. Many GPS data messages are
output less than 1 Hz due to the amount of data being
computed and transmitted. A position update of five times per
second is considered fast. For more information refer to
Specifications in Appendix B of the manual.
GPS/DGPS
Question: How do I know when my Axis
3
receiver has located
a GPS signal?
Answer: The easiest way is to look at the LED status indicators
on the receiver. See Section 4.2, Interpreting LED Indicators, page
27 for more information.
Question: How long does it take to get a DGPS lock?
Answer:
On normal power-up, you should have DGPS lock
within a few minutes. However, if this is the first time your
receiver has been powered up in a new region or if the almanac
has been reset, DGPS lock can take up to 30 minutes.
