"Yes, I've tested NEO-7M, it cannot simultaneously receive GPS and GLONASS signal. Currently most GLONASS capable modules on the market, only ublox-7 chipset based ones cannot simultaneously receive GPS and GLONASS signal. If GLONASS mode selected…"
"GPS module spec is one thing, performance of the final product with housing/cable sold to customer is another thing.
Different GPS products for UAV made by different company using same module (NEO-7M or LEA-6H) very likely would perform not the…"

"NEO-7M could only receive either GPS or GLONASS signal, cannot receive both GPS and GLONASS signal simultaneously. GLONASS alone accuracy is no better than GPS. NEO-7M's spec has GPS accuracy 2.5m CEP, GLONASS accuracy 4m, http://goo.gl/T5Veak.…"
"It is not NS-RAW receiver alone that gets RTK accuracy. NS-RAW is a GPS receiver with carrier phase raw measurement output. Open-source RTK software such as RTKLIB can be used to achieve RTK accuracy. NS-RAW is S1315F-RAW GPS module with USB and RF…"
"The $25/pcs NS-RAW module on the NavSpark Indiegogo campaign enables user to easily setup and experiment with RTK technology using open-source RTKLIB on a PC or laptop. As the operation is not like using a Garmin handheld, the suggested video demo…"
"Adding inertial sensor is helpful only in situation where there is signal blockage, providing continuous navigation for some time when GPS is not getting fix. Combining inertial sensor data with GPS measurement data to form Kalman Filter solution…"
"Only NS-RAW has carrier phase raw measurement output feature to work with RTKLIB to achieve centimeter-level accuracy. Offered as separate perk, to increase the chance of reaching funding goal. :-)"
"Since NavSpark has software development kit integrated into the provided Arduino IDE environment, users can easily program it to do other things at the same time GPS is working, or customize the NMEA output behavior to emulate other GPS module.…"
Our NavSpark Indiegogo campaign brings latest GPS / GLONASS / Beidou / QZSS / SBAS satellite navigation technology and high-precision centimeter-level accuracy RTK technology accessible for everyone. Arduino programmable feature make it simple to…
"GPS repeater or re-radiator basically amplify the signal of an outdoor GPS antenna then radiate the signal from an antenna placed indoor. As the outdoor antenna location is fix, the rebroadcast signal will always give fixed position of the outdoor…"
