range of temperatures, use the thermocouple peripheral.

5.3.2 Settings
Measurements can be scheduled as a multiple of the base-interval. The fastest possible measurement rate
is achieved by setting the interval to 1 in which case measurements will occur on every base interval. To
reduce power consumption, the measurement rate can be turned down by increasing the interval.
Warning and alarm thresholds for ambient temperature can be enabled. Once enabled, each time a
measurement is completed, the returned value will be compared with minimum and maximum warning
and alarm thresholds. If a warning or alarm level is breached, a message will immediately be transmitted.
As long as the warning or alarm condition persists, messages will be transmitted at the exception-interval
rather than the transmit-interval. Hysteresis can be specified in 1°C increments, to prevent multiple
alarms in the presence of fluctuating temperature.
A full list of temperature sensor settings is given in the table at the end of the chapter.
5.4 GPS
Models of the ORB that have GSM connectivity also have an integrated Global Positioning System (GPS).
The GPS receiver, with integrated antenna and LNA allows for position and speed based reporting. The
internal GPS will receive GPS, GLONASS, BeiDou and Galileo satellites to ensure high accuracy measure-
ment and fast time to first fix. Data available from the GPS includes:
• Latitude, longitude and height
• Speed (km/h) and bearing
• Date and time
• Number satellites being tracked
In order to utilise the GPS, the ORB needs to be mounted such that the internal antenna has visibility of
the sky. Plastic and fibreglass roof sheeting will have a minimal effect on GPS performance whereas rein-
forced concrete and metal roofs will render the GPS inoperable. In applications where GPS is required
but the ORB cannot be mounted in a position where the sky is visible, a GPS re-radiating antenna can be
used. Please make sure that the chosen re-radiating antenna is of high quality and legal for use in your
region. An advantage of good GPS signal quality is that the ORB will consume less power as acquisition
time will be less.
