The Ariane 5/THAICOM 4 (IPSTAR) mission was the 18th successful mission for the Ariane 5G Generic launcher, demonstrating its technical and operational maturity.
Provisional parameters at injection of the Ariane 5's storable propellant upper stage were:
- Perigee: 574.8 km for a target of 575 km (±3 km)
- Apogee: 35,875 km for a target of 35,894 km (±160 km)
- Inclination: 6.98 degrees for a target of 7.00 degrees (±0.06°)

Technology and Innovation
Thaicom 4 is a marvel of modern technology, with a 45 Gbit/s bandwidth capacity that allows for rapid deployment and flexible service locations within its footprint. This is made possible by its platform's ability to provide an immediately available, high-capacity ground network with affordable bandwidth.
The IPSTAR broadband satellite system is a key component of Thaicom 4, using a gateway earth station to communicate over the satellite and provide broadband packet-switched communications to a large number of small terminals with network star configuration.

Highly efficient transmission methods are employed, including Turbo Product Code (TPC) and higher order modulation (L-codes) for increased system performance. These forward channels use Orthogonal Frequency Division Multiplexing (OFDM) with a Time Division Multiplex (TDM) overlay.
The terminal-to-gateway direction uses narrow-band channels that operate in different multiple-access modes based on bandwidth-usage behavior, including ALOHA and TDMA for STAR return link waveform.
Increasing bandwidth by a factor of twenty compared to traditional Ku-band satellites translates into better efficiencies, despite the higher costs associated with spot beam technology. This results in a considerably lower cost per circuit compared to shaped beam technology.
IPSTAR's Dynamic Power Allocation optimizes the use of power among beams and allocates a power reserve of 20 percent to be allocated to beams that may be affected by rain fade, thus maintaining the link.
