The DP GPS
Haglöf Sweden’s DP II caliper works with different software-run
add-ons and accessories, designed to improve accuracy, efciency
and versatility. With add-on instruments mounted on the DP
caliper com-port, battery and display are supplied from the caliper.
The DP GPS module enables you to position and navigate
with your computer caliper as you are performing your regu-
lar eldwork. The DP GPS is attached to the host computer
and becomes an integrated part of your caliper. The module
is controlled through the DP caliper, runs with its battery,
display and processor, and leaves you with less worries about
charging time, connectivity and compatibility.
The DP GPS has a 33-channel high-sensitivity receiver that
supports several satellite systems such as GPS, Glonass, Galileo
and GZSS. The ability to use several satellites from different
systems at the same time improves positioning in difcult ter-
rain. The built-in real time correction allows for accuracy down
to 2.5m/8.19ft in open terrain. Algorithms can predict satellite
positions for up to 3 days, using data from last used satellite con-
stellation saved for up to one month in the GPS with a built-in
rechargeable battery.
Depending on software application in your DP II computer
caliper there are numerous ways to integrate the DP GPS mod-
ule in your eld cruising routine. Collect measuring data and
conenct with positions on sample plots, stand areas, areas with
special biotops, individual trees, and roadside timber loads. Make
a tracking log of borderlines in a plot and have the DP caliper
calculate the total area. Preload positions for marked trees and
hazard trees and navigate straight to them. Revisit an area, and
instantly nd your way. With all eld data registered, collected
and available in one secure place in your DP computer caliper,
no additional instruments or eld computers are needed. WIth
the DP caliper and DP GPS module you can save time and ensure
compliance. The GPS module is very small and will not affect
balance and weight of the DP II caliper when attached. Also avail-
able as a combination module including DP GPS and DME for
efcient ultrasound distance measuring in sample plots.
