Sampling Rate
:
Do not change
. Only 2-bit I / 2-bit Q / 4.092 MHz sampling rate is allowed
in the current firmware.
•
Elevation Mask
: In general, it is a good practice to ignore satellites that are near the
horizon due to signal fade, higher atmospheric delays and multipath. The default 8 degrees
is good for most use cases.
•
Session Name
: The default processing session name is the date and time of processing.
User can change the name of this processing session to anything that is deemed more
appropriate.
•
Latitude (dd.dd) & Longitude (dd.dd)
: Defines the rough initial position of the receiver. The
server will use this initial position to aid the satellite acquisition process and/or position
calculation. If these initial values do not produce a valid position, the server will then
automatically use an advanced Doppler positioning algorithm. The Latitude and Longitude
does not need to be overly accurate – anywhere within 100 Km should suffice.

DeviceID
: Refer to the “authcode_XX-XX-XX-XX.gc” file received from the AUTHCODE
Request process as outlined in section 3.2.5, “XX-XX-XX-XX” is the DeviceID of the Stamp
Module).

Google API Key
: Since late 2018, Google Maps started to charge for displaying maps
correctly on websites. If a Google Maps API Key is not defined, the following error message
will display on the map. If you have a valid Google Maps API Key, enter it here.

Testing the Stamp Module
When evaluating the Stamp Module, customers are encouraged to develop a formal test plan to
characterize the receiver performance. Test may include Time-to-First-Fix (TTFF), absolute and
relative location accuracy (static and kinematic scenarios), acquisition and time to re-acquire,
impact of multipath on absolute and relative accuracy, and power consumption etc.
