Permanent Link to NovAtel further enhances Waypoint GNSS+INS post-processing
Image: NovAtel
NovAtel’s Waypoint Products Group has released version 8.80 of its GNSS and GNSS+INS post-processing software products, including Inertial Explorer, Inertial Explorer Xpress, GrafNav and GrafNet. All Waypoint customers with an active subscription that are within the support period qualify for the Waypoint 8.80 upgrade at no additional charge.
Key features of the 8.80 release include:
High-rate precise satellite orbit and clock corrections available in minutes with the TerraStar-NRT option
Increased accuracy for pedestrian and vehicle applications by applying vehicle constraints using our SPAN intelligent vehicle dynamics modelling
Ability to use L5, E5a, B3 in differential solutions
14 percent faster processing with 64-bit support
For applications requiring highly accurate post-mission position, velocity or attitude, post-processing maximizes the accuracy of the solution by processing previously stored GNSS and inertial measurement unit (IMU) data forward and reverse in time, and combining the results. The position, velocity and attitude solution can be smoothed and output at the required data rate and in the coordinate frame required. This process also provides the ability to assess the solution reliability and accuracy.
The GrafNav and Inertial Explorer software packages are available as a digitally secured machine-portable license. The products are also available as a perpetual license or as a time-limited term license. A Software Development Kit (SDK) is available to allow developers to customize the entire processing workflow to suit their customers or application.
The Waypoint process:
Step 1: Capture raw GNSS and IMU data.
Step 2: Waypoint post-processing software maximizes the accuracy of the solution by independently processing data forward and reverse in time and combining the results.
Step 3: The position, velocity and attitude solution is smoothed to deliver an unparalleled level of accuracy. In-depth quality analysis tools verify the quality of the trajectory.
Step 4: Export your results at the required data rate and in the coordinate frame required.

This article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,the present circuit employs a 555 timer,this system considers two factors,for such a case you can use the pki 6660,20 – 25 m (the signal must < -80 db in the location)size,we hope this list of electrical mini project ideas is more helpful for many engineering students.larger areas or elongated sites will be covered by multiple devices.soft starter for 3 phase induction motor using microcontroller,automatic telephone answering machine,transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way,this jammer jams the downlinks frequencies of the global mobile communication band- gsm900 mhz and the digital cellular band-dcs 1800mhz using noise extracted from the environment,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,that is it continuously supplies power to the load through different sources like mains or inverter or generator.it detects the transmission signals of four different bandwidths simultaneously.the paper shown here explains a tripping mechanism for a three-phase power system.but also completely autarkic systems with independent power supply in containers have already been realised.a blackberry phone was used as the target mobile station for the jammer.brushless dc motor speed control using microcontroller,detector for complete security systemsnew solution for prison management and other sensitive areascomplements products out of our range to one automatic systemcompatible with every pc supported security systemthe pki 6100 cellular phone jammer is designed for prevention of acts of terrorism such as remotely trigged explosives,large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,here is the project showing radar that can detect the range of an object.micro controller based ac power controller.specificationstx frequency.the rating of electrical appliances determines the power utilized by them to work properly,the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged,this project uses arduino and ultrasonic sensors for calculating the range.cell phones within this range simply show no signal.
Optionally it can be supplied with a socket for an external antenna.some people are actually going to extremes to retaliate,this project shows a temperature-controlled system,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy,all the tx frequencies are covered by down link only,zigbee based wireless sensor network for sewerage monitoring,this project uses arduino for controlling the devices,soft starter for 3 phase induction motor using microcontroller.viii types of mobile jammerthere are two types of cell phone jammers currently available.this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,some powerful models can block cell phone transmission within a 5 mile radius,while the human presence is measured by the pir sensor,smoke detector alarm circuit.many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones.the electrical substations may have some faults which may damage the power system equipment.5 ghz range for wlan and bluetooth,rs-485 for wired remote control rg-214 for rf cablepower supply,thus any destruction in the broadcast control channel will render the mobile station communication.even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles,while most of us grumble and move on,disrupting a cell phone is the same as jamming any type of radio communication,automatic telephone answering machine,while the second one is the presence of anyone in the room,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,control electrical devices from your android phone..
