Narrative:
Loss of reception on both GPS units when departing the helipad. Ground units use this pad as an lz due to very few options available in that area. Loss of reception occurred at xa:40 and garmin 530 unit gave me the error message and reacquired satellites in about 10 sec and the garmin 430 unit took about 3-4 minutes to reacquire satellites. Reception was regained and no other anomalies.
