Highprecision Positioning Modules<br />
RF & Wireless<br />
u-blox has gained another highprofile<br />
endorsement for ZED-<br />
F9P, its high precision GNSS<br />
(Global Navigation Satellite<br />
System) module that delivers<br />
centimeter-level accuracy within<br />
seconds. Quantum-Systems, a<br />
German company specialized<br />
in the development and production<br />
of electric VTOL (Vertical<br />
Take-off and Landing) aircrafts<br />
for civilian use, has incorporated<br />
the module in its latest electric<br />
Tron F90+ fixed-wing unmanned<br />
aerial vehicles (UAVs). These<br />
state-of-the-art 3.5 m wingspan<br />
drone units, which can travel at<br />
speeds of up to 160 km/hour<br />
and have a <strong>10</strong>0 km flight range,<br />
are employed in mission-critical<br />
logistical activities – such as the<br />
transporting of emergency blood<br />
reserves to remote locations, as<br />
well as mining and agriculture<br />
related tasks.<br />
The Tron F90+ is the latest addition<br />
to the Quantum-Systems<br />
eVTOL UAV platform designed<br />
for cargo, inspection, survey and<br />
mapping, and reconnaissance in<br />
adverse conditions, and consisting<br />
also of the Trinity F9, Scorpion,<br />
and Vector UAVs. They all<br />
feature u-blox F9 high precision<br />
GNSS technology.<br />
The key challenge that the<br />
engineering team at Quantum-<br />
Systems faced when developing<br />
the Tron F90+ UAV concerned<br />
vertical take-off and landing<br />
(VTOL), and having access to<br />
accurate enough position data<br />
to ensure that these operations<br />
would always go smoothly. The<br />
valuable payloads being carried<br />
could thus be protected from risk<br />
of damage. Through the multiband<br />
real-time kinematic (RTK)<br />
Bluetooth LE Beacons Optimize Asset Tracking<br />
u-blox has announced that its<br />
Bluetooth low energy module<br />
NINA-B1 has been chosen by<br />
AddMobile, Swedish provider<br />
of devices and services for<br />
construction site management,<br />
as the basis of its short range<br />
equipment-tracking beacons,<br />
AddTrackers. This service is<br />
among the latest enhancements<br />
to the company’s AddMobile<br />
Toolbox platform and involves<br />
adding radio beacons to any<br />
tools or equipment that need<br />
tracking.<br />
The AddMobile Toolbox helps<br />
site managers control mobile<br />
work orders, log fleet vehicle<br />
mileages, secure entry to<br />
work sites, register staff as<br />
they come and go, as well as<br />
and raw code and carrier phase<br />
data available to the ZED-F9P,<br />
the necessary positioning correction<br />
is assured and the pilot can<br />
complete even the most difficult<br />
of maneuvers. Each of the Tron<br />
F90+ UAVs features a ZED-F9P<br />
module. Through either RTK or<br />
post-processing positioning correction<br />
absolute position accuracy<br />
can also be brought down to<br />
3-5 cm. This degree of accuracy<br />
means that the u-blox module is<br />
about <strong>10</strong>0 times more accurate<br />
than standard meter-level GNSS<br />
solutions, but is still able to present<br />
customers with very attractive<br />
pricing.<br />

handling fleet management<br />
and equipment safety. It uses<br />
a variety of hardware to enable<br />
these Connected Construction<br />
Site’s services, including stationary<br />
hubs and entrance control<br />
units with Bluetooth low<br />
energy and cellular connectivity,<br />
as well as an RFID reader,<br />
and mobile hubs with Global<br />
Navigation Satellite Systems<br />
(GNSS), Bluetooth low energy<br />
and cellular connectivity.<br />
In addition to NINA-B1, the<br />
AddMobile Toolbox features<br />
the u-blox GSM/GPRS cellular<br />
module SARA-G3 and<br />
the u-blox MAX-M8 GNSS<br />
module series.<br />
