Compression-01 and the other guard troops were not present at the time of Cold's death and Frieza's first death. As such it was unaware that the Dragon Team even existed, only being aware that Frieza and Cold had been killed upon invading Earth, after having the planet scouted and discovering the "strongest man" Mr. Satan, it and the other guard troops chose not to invade until he was dead, as they knew they could not deal with the one who defeated Frieza.
After Mr. Satan's death, the guard troops finally ordered the invasion of Earth in Age 820, leading to a full planet-wide conflict and many deaths, and finally culminating in a battle between the aged Z Fighters and the Galactic Frieza Army, Compression-01 survived the conflict and continued to act as a commander for the Frieza's army remnants years later.
Several robot models similar to Compression-01 also appear in Dragon Ball Online.
In Age 820, the guard troops noted that they would be no match for someone who could defeat Frieza.
