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.

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.

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.
