GPS (blue LED)
LED indicator is blinking: the logger has already obtained GPS fix and updated
its, coordinates, date and time accordingly.
4.3.4
External battery
The Orbit 360 data logger works with an external battery. We recommend using a
flotation (back-up) sealed lead-acid battery (12 VDC). This kind of battery has no
maintenance and can be transported in any orientation.

There are different consumption requirements according to the station configuration,
so there is no universal power supply system solution that fits every station. There are
several factors affecting the station consumption: hardware, communication mode,
sensors… For instance, satellite modem consumption is two times higher than GSM,
also, sites with low signal need more transmission power during telemetry sessions. The
number of telemetry sessions a week or the number and type of sensors may influence
as well. Other factors affecting electrical generation are latitude, solar radiation of the
site and panel orientation. We recommend using batteries of at least 24Ah, having that
way up to 2 months autonomy without be recharged.
Solar regulator and battery should be inside the same weather proof enclosure that
protects the logger. The solar regulator must be installed just next to the battery
because its charge control function depends on the battery temperature: this means
that the temperature of the regulators should be as close to the battery temperature as
possible.
