SP20 FAQ List
1. If I am only going to
use WAAS corrections but I want 30 cm accuracy should I purchase the
30 cm option? No, the accuracy options only enhance RTK
(where you are connected to a remote base) operation. SBAS/WAAS
performance is maximized in the basic product.
2. I purchased an SP20,
but the battery life is not as expected. The initial release
of product included 1/2 sized batteries. We expect to get full sized
batteries mid to late November and will automatically send you the
updated cells at no additional charge.
Will the SP20 generate RINEX data?
Yes it is possible to record static data from the 'Survey
Mobile; and 'Mobile Mapper Field' applications. The G-Files can be
converted to RINEX using the standard Spectra RINEX convertor.
Has the SP20 antenna been calibrated by NGS?
Yes, the antenna is currently (November 2018) being
calibrated and will be available for OPUS solutions.
How expensive is a RTX subscription?
$2,000 per year. Purchased online through the Trimble portal.
6. Is it possible to use an
external antenna with the SP20? Yes, the connector and cable
are identical to the cable used on the MobileMapper 120. You will
want to use a full GNSS antenna.
How does the SIM card fit into the
receiver? Insert the uSD card first, then insert the full
sized SIM card on top of the uSD:
8. Will the SP20 work as a phone? Yes,
the lower part is an Android phone and yes you will look like an
idiot using it as a phone, but the speaker phone is excellent:
9. Can you redirect NMEA from the SP20 via
Bluetooth to an external device? Yes, there are probably
several ways to do this, we use the 'Bluetooth GPS Output Paid'
application ($0.99) which can be found on the 'Play Store'.
