7.2 Specifications
7.2.1 Ground Units:
● In summary, the unit must operate (from a power off condition) with an
internal temperature ranging from -50C to +85C. The box performance
specifications will be over the usual range of -40C to +70C.
● The system shall survive immersion in fresh or salt water (maximum of
5 m) for up to 1 day and still function to specification.
● The unit is not expected to operate at depth, but it should not corrode
when submersed with battery packs. If the unit is self buoyant it will
still be subjected to the test by forced submersion.
● The system shall survive a 2 meter drop onto ¾ inch plywood on
concrete on any surface of the unit.
● This is the standard used by seismic manufacturer. Units will throw to
the ground and into the back of trucks and they must be able to
withstand this kind of shock
● The system shall have a removable antenna and still maintain its water
seal with the antenna removed
● The system shall have removable desiccant packs inside enclosures
● The WRU shall meet all system requirements after being opened and
closed for repair or maintenance in 95% humidity, 38°C environments.
● The battery pack shall have a shelf life of 1 year before needing a
recharge
● A LI-Ion cell at about 60% to 80% charge level it should last at least 12
months when kept at 23°C. This will reduce to about 3 - 6 months at
40°C and 1 - 3 months at 60°C.
● The battery pack shall have minimum of 48 watt hours of capacity
