PanAmSat in partnership with Australian Satellite
Services, provides global video and data broadcasting
service via satellite and fibre to over 98 percent
of the world’s population. As one of the world’s
leading satellite providers, with 24 satellites currently
in orbit, PanAmSat provides a true global network.

PanAmSat serves the Australian, New Zealand and Pacific
markets with the PAS-2 and PAS-8 satellites.
The PanAmSat On Demand Service is provided in the
Australian, New Zealand and Pacific region on the
PAS-2 and PAS-8 satellites.
Australia and New Zealand coverage in provided on
the PAS-2 Ku-Band footprint.
Australia, New Zealand, PNG and Pacific coverage
is provided on the PAS-8 C-Band footprint.
Or alternatively the PAS-2 C-Band footprint.
At the present time due to satellite coverage and
also regulatory environments PanAmSat does not offer
coverage of; the Cook Islands, Samoa, or Tonga.
On Demand Service
The PanAmSat On Demand Service is a totally IP based
service providing users with the flexibility of a
“one socket” (Ethernet) interface for
all IP applications.
PanAmSat has chosen technology from Vipersat Networks
to provide the On Demand service. The Vipersat system
utilizes a derivative of TDMA technology to provide
the “inbound” data link from the remote
user sites to the Network Hub based at Australian
Satellite Services in Adelaide, South Australia.
The Vipersat STDMA inbound link is configured to a
data rate selected by the user(s) to provide the IP
data throughput required. The remote user is also
provided with an “outbound” TDM link from
the Hub at a rate again designed to provide the IP
data throughput required.
An example could be a TDM Outbound link at a rate
of 1Mb and an STDMA Inbound link at a rate of 512kb.
Both links in this example would be shared by up to
10 remote users only. The network in this example
would operate in a similar mode to a terrestrial DSL
network based on the Uplink and Downlink speeds of
the network. As the network is wireless and totally
IP based it can also be likened to a terrestrial WiFi
The major difference between the PanAmSat on Demand
service, terrestrial DSL and other satellite networks
is that while the users will typically operate within
the STDMA network the system is designed to switch
the user to a dedicated link should an application
or load require this. The benefit of this system is
that the user operates in a true IP Bandwidth on Demand
environment where bandwidth can be allocated “on-the-fly”
and scaled as applications or load change. Bandwidth
is billed in 1kbps increments by the minute and has
a minimum bandwidth allocation of 10kbps and a maximum
of 5Mb (currently).
The above diagram shows two remotes communicating
with the Network Hub. One remote is operating on the
STDMA inbound link (red dotted line) as the remote
only has a LAN Client application running. The other
remote has been switched to a dedicated link (solid
green line) as an application (Video Conference) has
dictated that more bandwidth or a higher data rate
The above diagram shows the network having switched
to the MESH mode. In this example both remotes are
communicating directly with one another for a VoIP
and IP Video Conferencing link while still maintaining
connectivity with the Hub for network LAN or Internet
Australia & Oceania on Demand Service
The PanAmSat on Demand platform servicing the Australia
and Pacific region is controlled from the PanAmSat
Hub situated in Adelaide, South Australia. The Hub
is located at the Australian Satellite Services Teleport
in Thebarton a suburb of Adelaide. The service is
currently carried on the PAS-2 satellite in Ku-Band
(Transponders 6K and 7K) and provides coverage of
Australia and New Zealand as well as the potential
for Trans Tasman links for users requiring this facility.
Australian Satellite Services is operating the on
Demand service in partnership with PanAmSat and will
be acting as an Australian reseller of the service.
The Australian Satellite Services facility offers
connectivity to the Australian Internet Backbone through
a local fibre connection and is operated with provisions
for redundancy in power and transmission. A full Help
Desk facility is being established and will be run
by Australian Satellite Services.
PanAmSat plans to add the on Demand service to the
PAS-8 satellite in C-Band in the near future and also
to PAS-2 C-Band as the requirements arise. Provision
has also been made for a smaller Hub to be established
in New Zealand for this market as customer need dictates.
The costing of a remote terminal varies depending
on the facilities required at the remote. That is,
whether the remote will operate in STAR (Remote-to-Hub)
or MESH (Remote-to-Remote) configurations. The operation
of a MESH system will require an additional satellite
modem/router at the remote. Or more than one if multiple
MESH applications are required. Other factors such
as where the remote terminal is situated in the satellite
footprint will dictate what size antenna and transmit
system (BUC) is required.
The following diagram shows a typical remote configured
with a 1.8 Metre Antenna to operate on Ku-Band with
4 Watt Ku-Band BUC, LNB and CDM-570L modem/router.
The diagram also illustrates an additional (optional)
modem/router for MESH operation.
PanAmSat and Australian Satellite Services welcome
the opportunity to discuss with customers the possibility
of incorporating the terminal price into a total monthly
It should be noted that a number of Service Providers
in Australia and New Zealand offer a TDMA VSAT product
that offers similar features to the standard PanAmSat
STDMA service. The prices offered for the remote terminals
to operate with these systems can be considerably
lower than the PanAmSat product. However, with these
systems the user is locked into the TDMA Inbound link
and if it is oversubscribed or suffers from throughput
throttling then the user will suffer this degradation
without remedy. None of these TDMA VSAT systems offer
“dedicated” IP Bandwidth on Demand. It
should also be noted that VoIP and IP Video Conferencing
suffer degradation in a TDMA environment due to packet
loss and latency issues.
Australian Satellite Services offer a true “Enterprise”
solution where it is possible to set QOS levels on
VoIP and Applications so that a switch to dedicated
“On Demand” bandwidth is always made without
compromising the user’s requirements.
