Exploration telepresence improves communication in space

Exploration telepresence improves communication in space
When Apollo astronauts on the Moon spoke with Mission Control on Earth, there was a noticeable time gap between a statement from Tranquility Base and its immediate acknowledgment from Houston. The gap lasted almost three seconds, or ten times longer than human reaction times would account for. What was happening? The answer is simple: space. The Moon orbits far enough from Earth that light (and radio) take 1.3 seconds each way to travel the distance.

Aiding the testing of satellite communications

Aiding the testing of satellite communications
The launch of the Drone Payload Satellite Simulator, from RF and microwave components manufacturer AtlanTecRF, provides a transmit (Tx) to receive (Rx) loop-back in testing mostly compact and mobile satellite communications systems in-situ and without the need for connection via cables.

FPGA-based video processing platform developed for DSTL

Defence Science and Technology Laboratory (DSTL) has contracted a team, led by Plextek Services and including RFEL and 4Sight Imaging to tackle the problem of performing rapid evaluations of real time image processing functions and to simultaneously demonstrate the latest adaptive capabilities that modern FPGA-based system-on-chip architectures can deliver to defence and security surveillance applications, all within a minimised size, weight and power footprint.

How can a VHF radio setup overcome the radio horizon?

How can a VHF radio setup overcome the radio horizon?
For Very High Frequency (VHF) radio communication, range is a crucial consideration. In tactical situations when faced with obstacles and challenges, teams must be able to improvise, adapt and overcome them. The last thing they should have to worry about at those times is a lapse in communication. This is where a technically proven system solution, designed to overcome over-the-horizon communications, plays a crucial role.

How rapidly can HF radio be deployed for disaster recovery?

How rapidly can HF radio be deployed for disaster recovery?
  When natural disasters knock out crucial communications infrastructure, High Frequency (HF) radio works as an effective fallback solution. By getting the right equipment into place, response teams can establish secure channels for transmitting voice, text and data in and out of a disaster zone.

How secure is HF radio?

How secure is HF radio?
  Whether used for humanitarian, critical or military communications, security is essential in high frequency (HF) radio transmission. But just how secure is HF radio? It depends on the equipment being used.

Is there interoperability between HF and VHF radio?

Is there interoperability between HF and VHF radio?
  In tactical situations, personnel can maintain effective communication over short to medium distances with Very High Frequency (VHF) radio. However, teams in the field do not work in isolation; they depend upon the support and intelligence information relayed from command centres.
