Altec was an inhabited planet located in the Omega Sagitta planetary system. The system was located in the Alpha Quadrant. The atmosphere was capable of supporting humanoid lifeforms. In the early 2160s, this planet, and its twin Straleb, were colonized by an unnamed humanoid species. These twin planets form the Coalition of Madena, which was created by a treaty. Altec was the homeworld for the Altec inhabitants.
A conflict between Altec and Straleb nearly broke out in 2365 when the Straleb Jewel of Thesia was thought to have been stolen by Thadiun Okona, who was also accused of impregnating Yanar, the daughter of the leader of Altec, Debin.
Following a confrontation involving the Federation starship USS Enterprise-D, an Altec vessel and a Straleb security vessel, it was revealed that the jewel, which was in Okona's possession, was destined for Yanar, from Benzan, the heir of the jewel. (TNG: "The Outrageous Okona")
Although both the script and subtitles of this episode lists the planet as "Altec", the characters in the episode pronounce it "Atlec".
Straleb, a sister planet, was on a star chart that was seen in Star Trek Generations. The chart depicted the location of planets, stars, and star systems in the Alpha Quadrant. Based on the dimensions of the circles used to mark locations on the star chart seen in Generations, this planet was located relatively far from the Enterprise-D.
According to the Star Trek: Star Charts, on the chart "United Federation of Planets I", Omega Sagitta system was located in the Alpha Quadrant. This system, also known as Madena, was a single star system. Its primary was a Class F star with a magnitude of +3, which was ten times brighter than Sol.
