The  NO-1  thing  that  you need on  your
Business Aircraft :

  From the ground up to 51,000Ft Business Jets owners need to be connected from the ground to all
phases of flight without any interruptions.
The growth in In-Flight Connectivity (IFC) is being driven by the demand for an improved in-flight experience
and its ability to run more demanding applications.

Being connected in flight is no longer a luxury, but a requirement.

The expectations for high performance and uninterrupted connectivity regardless of the duration ,
location and phase of flight is a real thing.
Our space is covered with many satellites constellations offering many type of systems from
InmarSat/ IntelSat/ ViaSat in the GEO space to now Starlink and OneWeb/Eutelsat in the LEO space.
Transceivers suppliers are offering systems capable of connecting to multiple constellations and
provide seamless switchover between beams , satellites from GEO to LEO and back.

 BUSINESS JETS  CONNECTIVITY

 In 20 years from Magnastar Telephony, Baker, Audio International, and Lufthansa Cabin Management Systems , variable temperature LED Cabin lighting, to todays advanced cabin Network, and High Speed connectivity  systems , I have seen it all !

The one  thing  that is  now  a  game  changer  and  evolving  rapidly is to be CONNECTED !

10 years ago Business jet internet was a science fiction project.
Today this flipped around and is No-1 on customer list and is  a  requirement.
Be connected from your ground office all the way to 51,000ft is now real  and High bandwidth
for Multiple Video conferencing is the very basic need..

Replicating the home experience in an aircraft at 45,000 feet flying near 0.9Mach is a challenge.
On  ground in  an office building your station is not moving,  But  in an aircraft maneuvering in 3D  space, the antenna is in motion, the satellite is also in motion, latency varies depending on how far away the satellite is (GEO, MEO, LEO), and the connection can be interrupted as the system switches between satellite beams and/or between satellites.

On top we need back-up internet sources , multiple routers with seamless transfer.
Also one scenario  may be to install multiple systems on board an aircraft and allow the Smart router to make switch-over and optimize the cabin network to best take advantages of each system. 

See my Multipath US/CAN Patent CA 3091399 / WO2019/157601, this becomes a reality.


Which solution to install on an aircraft is a factor of the mission requirements , Flight profile , 
what are the passengers and crew trying to do .

Integration of Communication systems is for me not only work, but a passion.
From my  extensive  experience in  integration, design,  system analysis, Flight TEST and  customers needs,
I can provide  you   the best  guidance and specially what  THE BOOKS  DONT TELL YOU !

 SATELLITES MULTI-ORBIT CONNECTIVITY:

For practical purposes, home and office capacity is unlimited, latency is not a concern, and the connection is uninterrupted.
But providing this experience at 45,000 feet is a serious challenge.
It can be difficult to maintain an uninterrupted connection during a flight. All satellites have beams that transits during flight, and depending on the constellation and flight path, multiple satellites may be switched-over. LEO constellations require the most frequent beam and satellite changes, but with GEO it require the much less transitions but do have more latency.

To minimize the impact of beam and satellite changes, buffering may be a good technique.
Minimizing the impact of beam and satellite swaps is the most challenging on video teleconferencing using a LEO network.

Like latency, satellite transitions do not impact all applications equally. Applications that are able to buffer content, such as video streaming, or that do not require a steady connection, but web browsing , email, will not be impacted by satellite transitions.
The applications that require low latency, however, are most likely to be impacted by a satellite switch-over. Also the time to transition is not consistent across satellite types. The transition time is a function of how quickly the antenna can point to the new satellite and how quickly the network can re-establish the connection. Total transition times for GEOs will be on the order of 15-60 seconds and total transition times for LEOs will be on the order of 400 microseconds to 25 milliseconds.


LATENCY:
Latency is the amount of time it takes data to move from the aircraft to the satellite and then to the ground.
Because GEO satellites are relatively far away, it has latency at ~700 milliseconds.

LEO has the much lower latency, between 100-300 milliseconds.
For most applications, latency is not a factor and can be mitigated by techniques such as buffering where a block of data for a song or movie is downloaded ahead of it being displayed. Video conferencing applications, however, are impacted by latency. 

 

Today we have more and more possibilities:
from StarLINK, ViaSat/InmarSAT Ka, Satcom Direct Plane Simple Ku/Ka, GoGo- ATG-5G & Galileo, Amazon Kuiper and more....

With advanced Electronically Steered Antenna (ESA.) this new technology has already been tested and deployed over GEO, MEO, and LEO in Ku and Ka bands, including dual operations in GEO/LEO and seamless switchover between beams and satellites.

With new high throughput and small form factor ESA operating continuously over GEO then instantaneously switched to operate on LEO when it came into view, and then back to GEO after operating on LEO.

All this is a major advancement in Aviation connectivity. In flight you can watch a movie, stream content, co-workers can be on a video conference call, and guest can be using a SIP application or WiFi calling to talk to their family all simultaneously like it is done on ground.

High performance Connectivity is now here ....

To integrate those systems as per your type of Aircraft , flight profile and budget this is where I come in… !
