Although a Minitrack station could measure the angles to the satellites very accurately, using this information to determine an orbit required additional work.
- The location of the station must be known very accurately. Prior to satellites, each continent had their own surveying coordinate system, and the relationship between these systems was not known accurately.
- The time at the station must be known accurately. The solution was to set up an accurate clock at each station, and calibrate it by comparing to the radio transmissions of WWV.
- Since more than one observation is needed to determine an accurate orbit, the data from each station must be sent to a central location for orbit determination. This was difficult since the stations were located in radio quiet areas, which therefore had little communications infrastructure. The US army pitched in and built new communications facilities for the stations.

Famous quotes containing the words problems and/or technical:
“If we parents accept that problems are an essential part of lifes challenges, rather than reacting to every problem as if something has gone wrong with universe thats supposed to be perfect, we can demonstrate serenity and confidence in problem solving for our kids....By telling them that we know they have a problem and we know they can solve it, we can pass on a realistic attitude as well as empower our children with self-confidence and a sense of their own worth.”
—Barbara Coloroso (20th century)
“I rather think the cinema will die. Look at the energy being exerted to revive ityesterday it was color, today three dimensions. I dont give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.”
—Orson Welles (19151984)
