Accompanying the increasing international competition to develop space in recent years, the work in outer space is rapidly increasing since, in addition to the International Space Station (ISS), private US and other companies have begun building multiple commercial space stations, such as space hotels and space stations for scientific experiments. GITAI aims to replace astronauts with robots that can work for a long time while being remotely controlled from earth while in low earth orbit space stations to reduce the burden on astronauts, shorten the time it takes to perform work in space, and reduce costs.

Data Reduction and compression
Restricted capacity of network infrastructure in the space is not capable to transmit any visual data (high resolution 360° image) required for sense of remote presence due to excessive data size. Therefore, GITAI has developed unique technology to reduce data volume and to compress data to successfully reduce data of 360° camera with resolution of 2.7K from original data volume of 800 Mbps to average 2.5 Mbps.
Transmitting visual data required for sense of remote presence with general standards such as WebRTC and regular communication technology such as http causes a large software/transmission latency that deteriorate sense of remote presence also on the network infrastructure in the space. Thus, GITAI has developed unique P2P communication technology and Linux base OS based on our own protocol to successfully reduce the software latency for rendering image on VR terminal to 60 ms by transmitting data of 360° camera with resolution of 2.7K via Internet.
Workload reduction technology
Specification of PC (CPU) with countermeasure for space radiation becomes lower for equivalent to several generations compared to that of PC for used on the ground. Transmitting visual data required for sense of remote presence especially requires the specification of very high performance PC in the standard distribution technology. Thus, GITAI has successfully processed every process required for low-latency transmission of image of 360° camera with resolution of 2.7 K with ultra compact Intel PC (CPU: Core m3-6Y30) by our own load reduction technology.
NAT traversal system
GITAI has developed our own NAT traversal technology dedicated for low-latency communication for logging-in/out between operator and robot just by an account name (token), in order to enable synchronizing the operator and the remote control robot just by logging-in/out process on any net work infrastructure.
