Realtime Technology Systems Pty Ltd was established by Geoff Roberts in 1997 primarily to provide specialist QNX™ services to users of the QNX™ Real Time Operating System. Prior to establishing RTTS Geoff had become involved in the development and maintenance of the QNX4 drivers for the Comtrol RocketPort products - producing the first of the interrupt driven drivers on the ISA products and then the PCI products. Around 2003 Geoff wrote the first of the QNX6 drivers for both the RocketPort uPCI and Infinity products (PCI-X). Shortly after that a driver was produced for the RocketPort Express (PCI-E) products. Geoff maintains these drivers to this day for Comtrol.

RTTS became the Australian and New Zealand distributor for Comtrol in 2004.

Geoff has been joined by two of his sons - Michael and Lyle - who bring to the company high level technical engineering and science expertise. Both completed Bachelor of Science (Physics) and Bachelor of Engineering (Hons) degrees at the Australian National University (ANU). Michael majored in mechanical engineering and Lyle in electronics with a specific focus on high speed FPGA based optical interferometry and sensor processing. Michael completed a PhD in Materials Engineering in December 2015. Lyle graduated with a PhD in Optical Physics and Engineering in December 2016.
