The Aerostat
The
aerostat is a modern version of well proven aerostat designs,
the aim being to provide a camera platform with almost
‘infinite’ loiter time over a location. Advantages:
· The aerostat is a stable and totally silent aerial camera
platform.
· The aerostat’s avionics and camera systems are powered from
the ground through a power uplink integrated into the main
tether cable. This means almost infinite aerial loiter times -
the only limiting factors being the camera configurations (DVCAM
tape, for example) and extreme weather conditions.
·
The aerostat has a fibre optic downlink incorporated into the
main tether cable, allowing it to provide a direct feed to a
directing unit on the ground. The same facility can also be
provided through a microwave downlink fitted to the platform.
· The aerostat can operate below 60m (180 feet) without CAA
authorisation – although we use an integrated risk assessment
process that updates the CAA where appropriate. Above 60m, CAA
approval is required with 28 days advance notice. Planning with
all other interested parties – event organisers, councils,
police, etc. is included in the pre-event risk assessment
process.
·
Weather is a constraint for the aerostat. Wet conditions are
not desirable. High winds create swaying (yaw) on the cable, but
integral ‘damping’ and camera stabilisation cancels this out in
most cases when filming. Further reduction techniques have been
designed to reduce the yaw in confined - especially urban –
environments. To date the aerostat has operated comfortably in
sustained winds up to 40mph (Gale Force 4)
·
The aerostat’s payload lift (at sea level) is approx. 38 kg.
It can be launched within two hours and can remain airborne
continuously by day and by night.
·
Camera
configurations are totally flexible Currently, the aerostat is
configured for the simultaneous operation of an HD pod, 360
degree video (reduced to 180 degree coverage below the aerostat)
and a MW downlink (or data relay link). For night operations
(wildlife, security, etc.) infra-red or thermal imaging can be
fitted. In the case of crisis management situations an
environmental monitoring pod can be fitted.
·
Like the airship it is totally air portable.
