What is everyone thinking about the Satcom Direct and GoGo merger/acquisition?
I'm working on a project involving small aircraft that fly at low altitudes (around 5,000-10,000 feet) and relatively low speeds (around 100 knots). I'm wondering if it's theoretically possible to adapt a marine satcom solution for use on these aircraft. Specifically, I'm curious about whether the equipment could handle the different environmental conditions and maintain a reliable connection at these altitudes and speeds.
Has anyone here explored something similar or have insights on the feasibility of this idea? What challenges might arise in terms of connectivity, antenna design, or regulatory compliance?
I am a satcom operator in the USMC signed a 5 year getting out in 3 years looking to take a career in satcom when I get out. Any advice on what to do before I get out to greater my chances of success?
Hey all,
Not sure if this is the right place, but was wondering if anyone had a copy of a CPI 980a Antenna Control System manual. Any spec will work, we are just looking for general information.
Hello SATCOM community,
I'm Claus Beck, and I work with Gatehouse Satcom, a Denmark-based company specializing in satellite communications. At Gatehouse Satcom, we are on a mission to help enable 5G connectivity from satellites, based on open standards set by the 3GPP. I thought it would be interesting to share some insights into this fascinating area.
What is 5G NTN?
5G Non-Terrestrial Networks (NTN) involve extending 5G coverage beyond traditional ground-based systems by leveraging satellites. This technology could revolutionize connectivity, particularly in remote or underserved areas, by providing high-speed internet directly from space.
Why is 5G from Space Important?
Challenges and Opportunities
While the potential of 5G from space is vast, there are significant technical and regulatory challenges to address. However, these challenges also present opportunities for innovation and collaboration across the industry.
For those interested in a deeper dive into the topic, we've published some detailed articles that explain the fundamentals and challenges:
If your mobile provider offered you a subscription today that would cost a few dollars extra but give you extended coverage via satellites, is that something you would consider?
I'm looking forward to hearing your thoughts on the future of 5G from space.
Best regards,
Claus Beck
Hey, I started writing a satcom competition policy diploma thesis. Essentially it is a work which will describe the current state of the sector competition and will attempt to create a reccomedation for the policy framework.
Now I know that it was essentially very stupid, to get into this as the sources are scarce to say the least, but I want to continue with this regardless, because I just fucking love it.
Anyway, I recently came upon a great source for manufacturing in space (www.factoriesinspace.com) and I was wondering if there is anything like this for satcom?
And if not, do you know any reliable sources for things like constellation projections or costs of satellite constellations? (I only got the Quilty Space analysis on Starlink and the data from what Viasat wrote about their ViaSat-3 constellation)
Any help or comments are appreciated!
I'm having limited success sourcing these modules from reputable sources at reasonable prices. Is it still in production?
Hello!
I'm an entrepreneur at an early stage start up. I'm in at the stage where I'm testing out my hypothesis. I would like to talk to other entrepreneurs / product managers who use satellite buses for their own businesses.
Is anyone available to fill out a quick 5 min survey?
Thanks in advance!
Can someone please explain to me what Basic Alerting Channel is used for? Is it the one that's used for alerting people of disasters and etc.?
Hey guys,
Looking for some help with a Linkway issue and hoping someone might have some insight. Operating on STT 185s and our equipment all functions correctly until we try to send a CW through this modem. When given the command, the modem responds with “no response” and when given a command to soft reset it prompts “soft reset command rejected”. The issue is not resolved when consoling directly into the modem GUI as the command submits but does not initiate any CW. This problem occurs over 2 STTs, three laptops, and several modems, all swapped around with known functioning equipment and all having the same issue sending a CW for peak and poll. Linkways are all updated to the latest software versions and manager laptops are on a windows 7 maxview aperia of unknown version. TIA!

Hello, I’m sorting out the ins and outs of Iridium, right now I’m sorting out the composition of the system message. I am interested in messages like access desition notification and its components, when these messages arrive and in general, what does this mean in general, please, or share the articles
Starlink has deployed six direct to cell satellites which are intended to work with normal phones directly also Elon musk says he could use it with a normal unmodified phone without any special equipment in between
How it is technically possible for a normal LTE phone to be able to send data to a satellite (~500km distance) in normal LTE frequencies?
how it is possible to deal with power, time slot interference, ... problems with direct to cell?
Hello everyone!
I am studying the MIMO OFDM system for the link " Satellite- User on the ground". I am looking for simulation parameters for my system.
I compare BER vs SNR for different channel estimation techniques. What are typical SNR values for satellite communication? Can it be from 9 to 20 dB? is QPSK modulation used in satcom?
In calculating the antenna gain for the ground station we use the formula G_max = 10*log10(efficiency*(pi*D*f/c)^2), using the efficiency, the diameter, and the frequency.
In calculating the antenna gain for the satellite, I have seen that the following formula is used G_max = 10*log10(efficiency*(pi*70/sat3dB)^2), where sat3dB is the satellite half power beam width (in degrees).
So the question is: Can I use the first formula for the antenna gain of the satellite? And is the half power beam width used for design purposes, having in mind the desired illumination area footprint? Is there any other reason to use the satellite half-power beam width value?
Dear all,
I have been looking for some good RF-link simulation software. More specifically, I would like to simulate a satellite constellation over time and calculate the signal strength etc.
I already tried Matlab satellite toolbox which includes a Link budget tool but it doesn't give the ability to simulate a constellation over time. Do you know of any software which could do this?
Thanks!
