Figure 5:
Example current use for a Tile with a 3.3 V input from wake-up, GPS acquisition,
Transmit, Receive mode, and then sleep mode. Note the two breaks in the y-axis scale.
Transmissions from the Tile consist of short periods of high current draw conforming to the
following characteristics:
Parameter
Value
Note
Transmission Length
2.3 s
Length of transmission for sending a 200 byte
packet to space. Actual length may be shorter
with a smaller packet size
Transmission Energy
1.8 mW-hrs
(6.6 J)

transmission to space
Recovery Time
0.4s
When sending multiple messages, this is the
minimum amount of time that will pass before the
Tile will attempt another transmission
