EB-870A
 

EB-870A is an ultra miniature 10.5 x10.4 mm2
GPS and GLONASS engine board. It provides
superior navigation performance under dynamic
conditions in areas with limited sky view like
urban canyons. High sensitivity up to -165dBm
for weak signal operation without compromising
accuracy.
EB-870A series is your best choice for embedded
applications.
