Brettgabel, Mountain summit in Berchtesgaden Alps, Germany.

Brettgabel is a mountain in the Berchtesgaden Alps that rises to 1805 meters and is part of the Hoher Göll group. The summit sits near the Austrian border and can be reached from multiple directions via different hiking trails.

The Brettgabel is the end point of the northwest ridge of the Hohes Brett, which rises to 1805.2 m. Since autumn 2010, one of eight transmitters of the GALILEO Test and Development Environment (GATE) has stood just above the summit, simulating navigation satellites as a pseudolite. The summit is reached only by an unofficial, unmarked trail from the Hinterbrand car park, branching off about 50 metres after the barrier on the forest road toward the Jenneralmen.

The wooden summit cross with its summit book marks the Brettgabel, and the name itself refers to a board-like fork. Since autumn 2010 one of eight pseudolite transmitters of the Galileo test and development environment GATE has stood just above the summit, simulating navigation satellites for the European system.

The only route from the valley is an unofficial, unmarked trail from the Hinterbrand car park, branching off unsigned about 50 metres past the barrier on the forest road toward the Jenneralmen. It crosses an alpine meadow then scree and rock, takes about two hours, and requires sure-footedness plus a few short scrambling sections of the first grade.

Just above the Brettgabel, a pseudolite of the GATE test field for the Galileo satellite navigation system has stood since autumn 2010, one of eight such transmitters simulating navigation satellites. The summit itself carries a wooden cross with a summit register and a trigonometric survey point.
