I'm not the first to ask for a GPS+GLONASS module:

Nor the first to mention the NV08C:

But that wasn't a new-product request. I think it should be.
Here's why I think it's belongs at SFE:
If the module is $48, I'd rather not pay $160 for one on a breakout board. I understand, hackers gotta make money too, but c'mon.

This is a really sweet one, but again, it more-than-triples the price of the module.

(And that's before international shipping.)
My breakout wishlist would be:

Here's why I think it's belongs at SFE:
- Newark carries it, but they want me to pay $20 extra because they don't feel like stocking any in the US.
- Besides, I'd rather send my markup-money in SFE's direction.
- It's multi-constellation, for folks who want to move beyond GPS alone
- And, as of this spring, the new NV08C firmware supports raw-observables output. It's (by FAR) the most affordable module to do so. (http://www.nvs-gnss.com/news/65-nvs-tec ... eries.html)

- which makes it suitable for RTK and post-processing
- Anyone want 5cm positioning? Get two and run RTK. This is like the only module *ever* where owning two won't break the bank.
- the Piksi is sweet but not cheap and doesn't exist yet.. http://www.kickstarter.com/projects/swi ... s-receiver

My breakout wishlist would be:
- Populate-as-needed pads to supply power to an active antenna, or not.
- But supply the appropriate inductor and capacitor, so they don't have to be ordered separately?
- bridge-as-needed pads in the RF path for u.fl or SMA antenna connector.
- Both UARTs out to FTDI-friendly pin rows.
- Big silkscreen right under 'em "I/Os ARE NOT 5V TOLERANT!"
- Charging circuitry to use a supercap as backup power.
- Or pads for a con-cell holder.
- 1PPS signal brought out to its own GND-SIG-GND pin header.
- LEDs on ant_flag and sleep_flag.
- LEDs on VIN_A and VIN_D
- Separate regulators for VIN_A and VIN_D and VCCIO
- Populate-if-needed pads for a reset pushbutton. Or just stuff that on.
- pullup/pulldown jumpers on the five config pins
