GPS Receiver Demo and App Store Announcement

In a previous update Danny Webster, Principal RF Design Engineer at Lime Micro, demonstrated the open source GNU Octave software being used to both generate and plot WCDMA cellular (3G) signals. In this video, Danny takes us through another demo in which he was able to use Octave to receive and demodulate GPS signals.

In this video we see a low cost, window mounted active antenna connected to a USB 3.0 LimeSDR board, which Danny explains has been configured to use an on-board numerically controlled oscillator (NCO) to implement a low-IF system, which offers certain performance benefits over zero-IF systems. In addition to receiving signals from multiple satellites, Danny notes how the great overall system performance made it possible to measure variations in doppler shift also.

Over the course of the campaign we’ve had numerous backers ask about the availability of the Ubuntu app store. Earlier today Lime Micro and Canonical announced that work has started on this, with a view to making it available once the crowd funding campaign successfully reaches its $500,000 pledge goal. While both open source and proprietary applications could be published to the store, the announcement also makes it clear that any Lime developed applications will remain fully open source.

$289

LimeSDR

The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by the LimeSDR to all other devices.


$99

Acrylic Case

A layered acrylic case to protect your LimeSDR. Can be used with either USB Type A or micro USB Type B. Antenna not included - separate purchase available.


$599

LimeSDR with Aluminum Kit

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. This board comes with fancy aluminum casing. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a fancy Aluminum casing coated with high quality material, cables, and antennas for a quick set up.


$799

Ultimate LimeSDR With PCIe Interface

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a PCIe interface, cables and Antennas for a quick set up.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency range from 800-960 / 1710-2170/ 2400-2700MHz.


$169

GPIO Board

This stackable expansion board for the LimeSDR provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays. LimeSDR not included.


$79

Hacker Case

This custom acrylic case accommodates both a LimeSDR and a GPIO Board, and includes SMA connectors for all RF ports, two SMA connectors for clock I/O, and a 40 mm cooling fan. LimeSDR and GPIO Board not included.
