Felipe G. Nievinski commented on Oliver Huang's blog post 1"x1" Centimeter-Level Accuracy RTK Module
"Another technique worth trying: "for low-quality GNSS antennas ... wavelength-scale random antenna motion substantially improves the time to [single-frequency] integer ambiguity resolution." http://gpsworld.com/accuracy-in-the-palm-of-your-hand/"

Felipe G. Nievinski commented on Oliver Huang's blog post 1"x1" Centimeter-Level Accuracy RTK Module
"You might wish to consider the antenna-swap technique to speed up ambiguity resolution; here's a quotation from chap. 6 in the recent book by Leick et al. (2015), see doi:10.1002/9781119018612.ch6 for details:
6.4.3.4 Antenna Swap Technique 
 
In vi…"

Felipe G. Nievinski replied to Oliver Huang's discussion NS-RAW related topics in "NS-RAW" category
"Yes, you can take it to the field with no laptop after you solder NS-RAW to NavSpark's SD-logging adapter board, and plug in an external antenna and battery pack.
See a picture at http://www.navspark.com.tw/blog/welcome-to-navspark-community, near "…"

Felipe G. Nievinski replied to Mark Payne's discussion NS-RAW with adapter board
"May I suggest the adapter board product description be updated at the web store so as to mention NS-RAW is supported; currently it takes a lot of searching to find out. Thanks."

Felipe G. Nievinski replied to Felipe G. Nievinski's discussion Event marker for post-processed stop-and-go (~"RTK")
"Hi Julio.  Thanks for your comments.  
So you:
- use NS-RAW and export a RINEX file;
- record the occupation start and end times in the field using an external device;
- modify the RINEX file to insert the event flags;
- process the modified RINEX i…"

Felipe G. Nievinski replied to Kevin Terry's discussion Real-time RTK processing
"So to make it work in real-time, you used a radio link to receiver the base station's observations at the R-pi, which I assume was cable-connected to the rover.
Could you share more details about the radio link?

Felipe G. Nievinski replied to Aslak Grinsted's discussion Minimizing power consumption
"In trying to minimize power consumption while also keeping position uncertainty acceptable, it's preferable to maximize the uninterrupted session duration, so as to facilitate ambiguity resolution. E.g., it's better to have a single one-hour long se…"
