5 terms

electronically steered antenna (ESA) technical

"Gilat’s multi-orbit Sidewinder electronically steered antenna (ESA) as a future line-fit solution"

line-fit technical

"offering Gilat’s multi-orbit Sidewinder electronically steered antenna (ESA) as a future line-fit solution"

in-flight connectivity technical

"future line-fit solution for in-flight connectivity service providers"

In-flight connectivity is the service that lets passengers and crew use the internet, make calls, or transmit data while an aircraft is in the air, delivered through onboard Wi‑Fi, satellite links, or cellular handoffs. It matters to investors because it can create new revenue streams, improve customer satisfaction and loyalty, and influence operating costs and airline partnerships—similar to how offering reliable mobile internet can change a coffee shop’s appeal and sales mix.

multi-orbit technical

"Gilat’s multi-orbit Sidewinder electronically steered antenna (ESA)"

A multi-orbit system or service uses spacecraft, satellites or missions that operate in more than one orbital zone around Earth (for example low, medium and geostationary altitudes) rather than staying in a single orbit. For investors, multi-orbit capability can mean broader markets, better reliability and more flexible revenue options—like a delivery company that can use bikes, vans and trucks to reach different neighborhoods and load sizes.

forward-looking statements regulatory

"Certain statements made herein that are not historical are forward-looking within the meaning"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
