In addition, there is no coverage gap in the northern hemisphere, for which the payload was originally designed. We have not received data since then. We are working on re-establishing the downlinks. The Aerobot is returning data on an hourly basis as planned. However, the ground speed returned by the Aerobot GPS unit is in error.
Values are much higher than the balloon's actual speed.
The altitude values may also be inaccurate. The Data page. Values for ground speed on the Solo Spirit home page are correct, because they are computed at Mission Control based on the balloon's known position. The Aerobot Science Payload has been installed on the Solo Spirit gondola. Tests of the Aerobot and its communications system have been conducted between Mendoza and Solo Spirit Mission Control at Washington University, St. Louis.
